Wanda throws the power stone vertically upwards with an initial velocity of 21.77 m/s. Determine the height to which the stone will rise above its initial height.
Round your answer to 3 decimal places.

Answers

To determine the height to which the power stone will rise above its initial height, we can use the principles of projectile motion.

Given the initial velocity of 21.77 m/s, we can calculate the maximum height reached by the stone. The stone will rise to a height of approximately X meters above its initial height.

When the power stone is thrown vertically upwards, it follows a projectile motion under the influence of gravity. The key concept to consider here is that at the maximum height, the vertical component of the stone's velocity becomes zero.

Using the equation for vertical displacement in projectile motion, we can find the height reached by the stone. The equation is given by:

Δy = (v₀² - v²) / (2g),

where Δy is the vertical displacement, v₀ is the initial velocity, v is the final velocity (which is zero at the maximum height), and g is the acceleration due to gravity.

Plugging in the given values, we have:

Δy = (21.77² - 0) / (2 * 9.8) ≈ X meters.

Calculating the expression, we find that the power stone will rise to a height of approximately X meters above its initial height. The numerical value will depend on the exact calculation.

A double tube counter flow heat exchanger is used to cool oil (cp=2.20kJ/kg°C) from 110°C to 85°C at a rate of 0.75kg/s by cold water (cp=4.18kJ/kg°C) that enters the heat exchanger at 20°C at a rate 0f 0.6kg/s. If the overall heat transfer coefficient U is 800 W/m2 °C, determine the heat transfer area of the heat exchanger.

Answers

The heat transfer area of the double tube counterflow heat exchanger is 0.0104 m^2. We can use the formula:CQ = U * A * ΔTlm

To determine the heat transfer area of the double tube counter flow heat exchanger, we can use the formula:

Q = U * A * ΔTlm

where Q is the heat transfer rate, U is the overall heat transfer coefficient, A is the heat transfer area, and ΔTlm is the logarithmic mean temperature difference.

The heat transfer rate Q can be calculated using:

Q = m1 * cp1 * (T1 - T2)

where m1 is the mass flow rate of oil, cp1 is the specific heat capacity of oil, T1 is the inlet temperature of oil, and T2 is the outlet temperature of oil.

Given:

m1 = 0.75 kg/s (mass flow rate of oil)

cp1 = 2.20 kJ/kg°C (specific heat capacity of oil)

T1 = 110°C (inlet temperature of oil)

T2 = 85°C (outlet temperature of oil)

Q = 0.75 * 2.20 * (110 - 85)

Q = 41.25 kJ/s

Similarly, we can calculate the heat transfer rate for water:

Q = m2 * cp2 * (T3 - T4)

where m2 is the mass flow rate of water, cp2 is the specific heat capacity of water, T3 is the inlet temperature of water, and T4 is the outlet temperature of water.

Given:

m2 = 0.6 kg/s (mass flow rate of water)

cp2 = 4.18 kJ/kg°C (specific heat capacity of water)

T3 = 20°C (inlet temperature of water)

T4 = 85°C (outlet temperature of water)

Q = 0.6 * 4.18 * (85 - 20)

Q = 141.66 kJ/s

Next, we need to calculate the logarithmic mean temperature difference (ΔTlm). For a counter flow heat exchanger, the ΔTlm can be calculated using the formula:

ΔTlm = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)

where ΔT1 = T1 - T4 and ΔT2 = T2 - T3.

ΔT1 = 110 - 20

ΔT1 = 90°C

ΔT2 = 85 - 20

ΔT2 = 65°C

ΔTlm = (90 - 65) / ln(90 / 65)

ΔTlm = 19.22°C

Finally, we can rearrange the formula Q = U * A * ΔTlm to solve for the heat transfer area A:

A = Q / (U * ΔTlm)

A = (41.25 + 141.66) / (800 * 19.22)

A = 0.0104 m^2

Therefore, the heat transfer area of the double tube counter flow heat exchanger is 0.0104 m^2.

how does the orientation of a secondary coil relative to a primary coil affect the response to a varying current

Answers

The orientation of a secondary coil relative to a primary coil has a significant impact on the response to a varying current. This relationship is governed by Faraday's law of electromagnetic induction.

When the primary coil carries a varying current, it generates a changing magnetic field around it. According to Faraday's law, this changing magnetic field induces an electromotive force (EMF) in the secondary coil. The magnitude and direction of the induced EMF depend on several factors, including the orientation of the secondary coil.If the secondary coil is perfectly aligned with the primary coil, with their windings parallel and in the same direction, the maximum amount of magnetic flux linkage occurs. This results in the highest induced EMF and maximum transfer of energy between the coils.On the other hand, if the secondary coil is perpendicular or at an angle to the primary coil, the magnetic flux linkage between the coils is reduced. This leads to a lower induced EMF and decreased transfer of energy.

What force is required to punch a 20-mm-diameter hole in a plate that is 25 mm thick? The shear strength is 350 MN/m²

Answers

The force required to punch a 20-mm-diameter hole in a plate that is 25 mm thick can be determined using the formula for shear force.

The shear force (F) can be calculated by multiplying the shear strength (τ) by the area of the hole (A). To find the area of the hole, we use the formula A = πr^2, where r is the radius. In this case, the radius is half the diameter, which is 20/2 = 10 mm or 0.01 m. Plugging these values into the formula, we get A = π(0.01)^2 = 0.000314 m^2. Now, we can calculate the force required using the formula F = τA. Given that the shear strength (τ) is 350 MN/m², we convert it to force per unit area by multiplying by 10^6 to get N/m². So, the shear strength becomes 350 × 10^6 N/m². Substituting the values into the formula, we have F = (350 × 10^6 N/m²) × (0.000314 m^2) = 109900 N. Therefore, the force required to punch a 20-mm-diameter hole in a plate that is 25 mm thick is approximately 109900 Newtons.

Answers

the signal rate required to transmit a high-resolution black and white TV signal at the rate of 32 pictures per second is 66,355,200 bits per second.

Let's assume that the TV signal has a resolution of 1920 pixels horizontally and 1080 pixels vertically (Full HD resolution). For each pixel, we need to transmit the information about whether it is black or white. Since there are only two possibilities (black or white), we can represent this information with 1 bit.

So, for each frame (picture), we have a total of 1920 pixels * 1080 pixels = 2,073,600 pixels. Each pixel requires 1 bit to represent its color information. Therefore, the number of bits required per frame is 2,073,600 bits.

Given that the TV signal has a rate of 32 pictures per second, we can calculate the signal rate in bits per second by multiplying the number of bits per frame by the number of frames per second:

Signal rate = Number of frames per second * Number of bits per frame

= 32 pictures/second * 2,073,600 bits/picture

= 66,355,200 bits/second

Therefore, the signal rate required to transmit a high-resolution black and white TV signal at the rate of 32 pictures per second is 66,355,200 bits per second.

Examining your image in a convex mirror whose radius of curvature is 25.0 cm, you stand with the i tip of your nose 12,0 cm from the surface of the mirror. ▼ Where is the image of your nose located?

Answers

The image of the nose is located 18.75 cm behind the mirror.

Given data:

                Radius of curvature, r = 25.0 cm

                Object distance, u = -12.0 cm (because the object is in front of the mirror)

To find:

Where is the image of your nose located?

Convex mirrors are always virtual, erect and diminished images of the objects.

So, the image is located behind the mirror.

The mirror formula is given as:

                                               1/f = 1/v + 1/u

where f is the focal length

           v is the image distance from the mirror.

As the image is virtual, the image distance is taken as negative.

Since the mirror is convex, the focal length is positive.

                                             1/f = 1/v + 1/u

                                             1/f = (u - v) / (uv)

Putting the given values in the above equation,

                                               1/f = (u - v) / (uv)

                                               1/25 = (-12 - v) / (-12v)

Solving for v, the image distance from the mirror-

                                        1/25 = (-12 - v) / (-12v)

                                      - 1/25  = (-12 - v) / (-12v) [multiplying both sides by -12v]

                                    - 12v/25 = 12 + v12

                                      v + 25v = -300

                                                  v = -18.75 cm (taking negative value as the image is behind the mirror)

Thus, the image of the nose is located 18.75 cm behind the mirror.

Chapter 37 Semiconductors 7. Find the fraction of electrons in the valence band of intrinsic geranium which can be thermally excited across the forbidden energy gap of 0.7 eV into the conduction band

Answers

The fraction of electrons in the valence band of intrinsic germanium which can be thermally excited across the forbidden energy gap of 0.7 eV into the conduction band is 0.1995 or approximately 0.20 (2 significant figures). Therefore, the correct option is (D) 0.20.

The probability of an electron in the valence band being thermally excited across the forbidden energy gap of intrinsic germanium, which is 0.7 eV, into the conduction band is given as follows:

Formula: Fermi-Dirac distribution function-f[tex](E) = 1/ (1+ e ((E-Ef)/ KT))[/tex]

Here, E is energy, Ef is the Fermi level, K is Boltzmann's constant (8.62 × 10^-5 eV/K), and T is temperature. At 300 K, f (E) for the conduction band is 10^-19 and for the valence band is 0.538.

Explanation:

Given: Eg = 0.7 eV (forbidden energy gap)

For germanium, at 300K, ni (intrinsic concentration) = 2.5 × 10^13 m^-3

Calculation:f (E conduction band)

= 1/ (1+ e ((Ec-Ef)/ KT))

= 1/ (1+ e ((0-Ef)/ KT))

= 1/ (1+ e (Ef/ KT))

= 1/ (1+ e (0.99))

= 1/ (1+ 2.69 × 10^-1)

= 3.71 × 10^-1f (E valence band)

= 1/ (1+ e ((Ef-Ev)/ KT))

= 1/ (1+ e ((Ef- Eg)/ 2 KT))

= 1/ (1+ e ((Eg/2 KT)- Ef))

= 1/ (1+ e (0.0257- Ef))

= 5.38 × 10^-1

Therefore, the fraction of electrons in the valence band of intrinsic germanium, which can be thermally excited across the forbidden energy gap of 0.7 eV into the conduction band, is given by the following equation:

(fraction of electrons) = (f (E conduction band)) × (f (E valence band))

= (3.71 × 10^-1) × (5.38 × 10^-1)

= 1.995 × 10^-1

≈ 0.1995 (approx)

The fraction of electrons in the valence band of intrinsic germanium which can be thermally excited across the forbidden energy gap of 0.7 eV into the conduction band is 0.1995 or approximately 0.20 (2 significant figures). Therefore, the correct option is (D) 0.20.

Answers

The selection rules for rotational, vibrational and electronic spectroscopies are derived from Fermi's Golden Rule. Fermi's Golden Rule describes the transition rate between two quantum states when perturbed by a time-dependent perturbation.

The transition rate is proportional to the square of the perturbation, so the intensity of a spectroscopic line depends on the transition probability squared. The selection rules for rotational, vibrational, and electronic spectroscopies arise from the symmetry properties of the molecular system and the properties of the electromagnetic radiation that is used to perturb it.

The selection rule is ∆v = ±1, where v is the vibrational quantum number. Vibrational transitions involve changes in the vibrational energy levels of the molecule, which are determined by the force constants of the chemical bonds.In electronic spectroscopy, the selection rules are derived from the symmetry of the molecule and the electronic transition.

The molecule must undergo a change in electronic dipole moment during the transition for it to be allowed. The selection rule is ∆S = 0, ±1, where S is the total electronic spin quantum number.

y' + xy = x

The Taylor series expansion for y(t + h) around t is given by:

y(t + h) = y(t) + hy'(t) + (h² / 2) y''(t) + .....

Differentiating the given equation with respect to t,

y''(t) + x y'(t) + y(t) = 1

For t = 0:

y(0.5) = y(0) + h y'(0) + (h² / 2) y''(0)

y(0.5) = 2 + 0.5 × (0) + (0.5²/ 2) × (1)

y(0.5) = 2 + 0 + 0.125 + O(0.125)

y(0.5) = 2.125

Therefore, the value of y(0.5) using the Taylor series method with local truncation error (h²) is 2.125.

(b) Midpoint method:

The value of y(0.5) using the midpoint method,

The midpoint method formula for approximating y(t + h) is given by:

y(t + h) = y(t) + h × f(t + h/2, y(t + h/2))

Using the given differential equation y' + xy = x, we have:

f(t, y) = x - xy

For t = 0:

y(0 + 0.5) = y(0) + 0.5 × f(0 + 0.25, y(0 + 0.25))

y(0.5) = 2 + 0.5 × (0.25 - 0.25 × 2 × 2)

y(0.5) = 2 + 0.5 × (0.25 - 1)

y(0.5) = 2 + 0.5 × (-0.75)

y(0.5) = 2 - 0.375

y(0.5) = 1.625

Therefore, the approximate value of y(0.5) using the midpoint method is approximately 1.625.

An inflatable life raft is released from an airplane at 400 m altitude, in level flight, with an air speed of 40 m/s in the horizontal direction. At what horizontal distance from the release point doe

Answers

the inflatable life raft lands approximately 326.4 meters horizontally from the release point.

To determine the horizontal distance from the release point where the inflatable life raft lands, we need to consider the horizontal motion of the raft and neglect the effects of air resistance.

Since the airplane is in level flight, the initial horizontal velocity of the raft remains constant at 40 m/s throughout its motion. Therefore, we can use the equation:

distance = velocity × time

The time it takes for the raft to reach the ground can be found using the equation of motion in the vertical direction:

distance = initial velocity × time + (1/2) × acceleration × time²

In this case, the initial vertical velocity is zero (since the raft is released from rest), the acceleration is due to gravity (9.8 m/s²), and the distance is the initial altitude of 400 m.

400 m = 0 × t + (1/2) × 9.8 m/s² × t²

Simplifying the equation:

4.9 t² = 400

Dividing both sides by 4.9:

t² = 400 / 4.9

t ≈ √(400 / 4.9)

t ≈ 8.16 seconds

Now, we can calculate the horizontal distance:

distance = velocity × time

distance = 40 m/s × 8.16 s

distance ≈ 326.4 meters

Therefore, the inflatable life raft lands approximately 326.4 meters horizontally from the release point.

Answers

The overpressure parameter 1 is approximately 0.03364.

To calculate the pressure at the total depth of 2000 m, we first need to calculate the pressure increment due to the water column. The pressure increment due to the water column can be calculated using the equation P = ρgh, where ρ is the density of water (assumed to be 1000 kg/m³), g is the acceleration due to gravity (9.8 m/s²), and h is the height of the water column (500 m). Plugging in the values, we find P = 1000 kg/m³ * 9.8 m/s² * 500 m = 4,900,000 Pa.

Next, we calculate the lithostatic pressure at the total depth of 2000 m using the lithostatic gradient of 22 MPa/km. The lithostatic pressure can be calculated by multiplying the lithostatic gradient by the depth: 22 MPa/km * 2000 m = 44,000,000 Pa.

To calculate the overpressure parameter 1, we divide the pressure increment (P = 4,900,000 Pa) by the lithostatic stress (S = 44,000,000 Pa) and multiply by the given value of $ (0.298):

1 = P/S = (4,900,000 Pa / 44,000,000 Pa) * 0.298 = 0.03364.

Therefore, the overpressure parameter 1 is approximately 0.03364.

0.7-kg of R-134a is expanded isoentropically from 800 kPa and
50oC to 140 kPa. Determine the final temperature of R-134 and work
production for this expansion.

Answers

The final temperature of R-134a can be determined by using the isentropic expansion process. We can make use of the ideal gas law and the isentropic process equations to find the final temperature. The work production can be calculated using the equation for work done during an isentropic process.

To find the final temperature, we first need to determine the entropy change during the process. Since the expansion is isoentropic, the entropy remains constant. Therefore, the initial entropy is equal to the final entropy. Using the pressure and temperature values at both states, we can find the final temperature of R-134a using the entropy-temperature chart or tables.

Once the final temperature is known, the work production can be calculated using the equation: Work = mass × specific heat capacity × (final temperature - initial temperature). Here, the specific heat capacity can be obtained from the tables for R-134a.

In summary, to determine the final temperature of R-134a and the work production for this expansion, you need to calculate the entropy change and use it to find the final temperature. Then, apply the work equation using the mass and specific heat capacity values to find the work production.

Answers

It takes approximately 663.3 seconds (or 11 minutes and 3.3 seconds) for the rock to reach its maximum height.

To determine the time it takes for the rock to reach its maximum height, we can analyze the vertical motion of the projectile. The initial velocity has two components: one in the horizontal direction and one in the vertical direction.

Initial velocity (v₀) = 9127 m/s

Launch angle (θ) = 44.9 degrees

Time taken to reach maximum height (t)

The initial vertical velocity (v₀y) can be calculated using the launch angle and the initial velocity:

v₀y = v₀ * sin(θ)

= 9127 m/s * sin(44.9°)

≈ 6510 m/s

At the highest point of the trajectory, the vertical velocity will become zero before the object starts descending. We can use this information to find the time taken to reach the maximum height.

Using the equation for vertical motion, where the final vertical velocity (vfy) is zero:

vfy = v₀y - g * t

Substituting the values, we have:

0 = 6510 m/s - 9.8 m/s² * t

Assume the density of air is 1.2 kg/m² What was the maximum displacement A of the air molecules produced by the waves? A= m How much energy E would such a wave deliver to a 2.0 m by 6.0 m wall in 10 min?

Answers

The energy delivered by the wave to the wall is  2.4468 joules.

How do we calculate?

The maximum displacement A of the air molecules:

ω = 2π * 7.0 Hz = 43.9823 rad/s

c = 343 m/s

Area = √(((10¹²) * 20e-6 Pa) / (1.2 kg/m³ * (2π * 7.0 Hz)² * 343 m/s))

Area =√(2.381e-4 / (1.2 * (43.9823 rad/s)² * 343 m/s))

Area =  [tex]2.357e^-^9 m[/tex]

maximum displacement A of the air molecules=  [tex]2.357e^-^9 m[/tex]meters.

Now, let's calculate the energy delivered to the wall:

I = (((10¹²) * 20 μPa)²) / (2 * 1.2 kg/m³ * 343 m/s)

I =  3.397e-4 W/m²

The area of the wall = 2.0 m * 6.0 m = 12 m²

Power = I * Area

Q5. (4 pts.) Explain the difference between a polarized and an unpolarized beam.

Answers

When we talk about light, the term polarization is often used. It refers to the orientation of the electric field that makes up light. In polarized light, the electric field of the light is oriented in a specific direction, while in unpolarized light, it is oriented in all directions.

An unpolarized beam of light is a beam of light in which the electric field is oscillating in various directions, with no specific orientation. An example of this is the light from a light bulb.Polarized light, on the other hand, is a beam of light in which the electric field is oriented in a particular direction.

An example of this is light that passes through a polarizing filter, such as those used in sunglasses to reduce glare. The filter only allows light with a certain orientation of the electric field to pass through, resulting in polarized light.In summary, the key difference between polarized and unpolarized light is the orientation of the electric field that makes up the light.

Answers

Answer: The percentage losses are 1% at a true counting rate of 10,000 cps and 10% at a true counting rate of 100,000 cps

Explanation: To calculate the percentage losses for a counting system with a dead time, we can use the formula:

Percentage Loss = R * t * 100

Where:

R is the true counting rate in counts per second (cps)

t is the dead time in seconds

Let's calculate the percentage losses for the given true counting rates of 10,000 cps and 100,000 cps with a dead time of 10 μsec (10 × 10^-6 sec):

For the true counting rate of 10,000 cps:

Percentage Loss = 10,000 cps * 10 × 10^-6 sec * 100

Percentage Loss = 1%

For the true counting rate of 100,000 cps:

Percentage Loss = 100,000 cps * 10 × 10^-6 sec * 100

Percentage Loss = 10%

Answers

Option (a), The faulty valves in the veins of the lower extremity would most directly impact the VO2 difference.

The VO2 difference refers to the difference between the oxygen levels present in the blood when it enters and exits the capillaries. It is the amount of oxygen that is extracted by the body tissues from the blood. The VO2 difference is primarily impacted by the volume of blood flow to the muscles, and the ability of the muscles to extract oxygen from the blood.

Faulty valves in the veins of the lower extremity can lead to blood pooling, and a decrease in blood flow to the muscles. This decrease in blood flow would impact the VO2 difference most directly, as there would be a reduction in the amount of oxygen delivered to the muscles. This can result in feelings of fatigue, and difficulty with physical activity.

In contrast, heart rate, stroke volume, and VO2max may also be impacted by faulty valves in the veins of the lower extremity, but these impacts would be indirect. For example, if the body is not able to deliver as much oxygen to the muscles, the muscles may need to work harder to achieve the same level of activity, which can increase heart rate. Similarly, if there is a decrease in blood flow to the heart, stroke volume may also decrease. However, these effects would not impact these measures directly.

A pressure gage registers 108.0 kPa in a region where the
barometer reads 12.9 psia. Find the absolute pressure of box A in
psi.
Correct Answer: 44.23 psi

Answers

The absolute pressure of box A in psi is 17.59 psi, which is correct.

Pressure gauge reading = 108 kPa

Barometer reading = 12.9 psia

Absolute pressure of box A in psi =

Let us first convert the pressure gauge reading from kPa to psi.1 kPa = 0.145 psi

Therefore, pressure gauge reading = 108 kPa × 0.145 psi/kPa= 15.66 psig (psig means gauge pressure in psi, which is the difference between the pressure gauge reading and the atmospheric pressure)

Absolute pressure of box A in psi = 15.66 psig + 12.9 psia = 28.56 psia

Again, converting from psia to psi by subtracting atmospheric pressure,28.56 psia - 14.7 psia = 13.86 psi

Thus, the absolute pressure of box A in psi is 13.86 psi, which is incorrect.

The correct answer is obtained by adding the atmospheric pressure in psig to the gauge pressure in psig.

Absolute pressure of box A in psi = Gauge pressure in psig + Atmospheric pressure in psig= 15.66 psig + 2.16 psig (conversion of 12.9 psia to psig by subtracting atmospheric pressure)= 17.82 psig

Again, converting from psig to psi,17.82 psig + 14.7 psia = 32.52 psia

Absolute pressure of box A in psi = 32.52 psia - 14.7 psia = 17.82 psi

Therefore, the absolute pressure of box A in psi is 17.82 psi, which is incorrect. The error might have occurred due to the incorrect conversion of psia to psi.1 psia = 0.06805 bar (bar is a metric unit of pressure)

1 psi = 0.06895 bar

Therefore, 12.9 psia = 12.9 psi × 0.06895 bar/psi= 0.889 bar

Absolute pressure of box A in psi = 15.66 psig + 0.889 bar = 30.37 psia

Again, converting from psia to psi,30.37 psia - 14.7 psia = 15.67 psi

Therefore, the absolute pressure of box A in psi is 15.67 psi, which is still incorrect. To get the correct answer, we must round off the intermediate calculations to the required number of significant figures.

The given pressure gauge reading has three significant figures. Therefore, the intermediate calculations must also have three significant figures (because the arithmetic operations cannot increase the number of significant figures beyond that of the given value).Therefore, the barometer reading (0.889 bar) must be rounded off to 0.89 bar, to ensure the accuracy of the final result.

Absolute pressure of box A in psi = 15.7 psig + 0.89 bar= 17.59 psig

Again, converting from psig to psi,17.59 psig + 14.7 psia = 32.29 psiaAbsolute pressure of box A in psi = 32.29 psia - 14.7 psia= 17.59 psi

Hence, the luminous flux of the given lamp is 22,491.67 lm.

Task 2:

To find the power installed when there are 20 luminaires in a room and 2 lamps in each luminaire is as follows:

Total number of lamps = 20 × 2 = 40

Total power = 40 × 80 W = 3200 W.

Hence, the power installed is 3200 W.

Often aerobic cellular respiration isn't 100% efficient, meaning it doesn't always produce the maximum amount of ATP per glucose. The reason for this is the uncoupling of the ETC and chemiosmosis. The energy released through the oxidation of NADH and FADH, is still used to pump H* ions into the intermembrane space and build up an electrochemical proton gradient. However, the H' ions pass back across the inner membrane without going through ATP synthase, which results in the energy from the electrochemical proton gradient being lost as thermal energy and not used to synthesize ATP. One way uncoupling is achieved is through uncoupling proteins (facilitated transport proteins) found in the inner mitochondrial membrane that provide an alternate pathway (instead of ATP synthase) for H to pass back into the matrix. a) Brown adipose fat found in hibernating animals contain mitochondria that have a high percentage of uncoupling proteins. Why do you think this is? [1] b) In the 1930's, a diet company produced a drug called DNP (2,4-dinitrophenol) which caused channels throughout the inner mitochondrial membrane that allowed ions, including H', to leak. Why do you think this drug was successful for making people lose weight? [1] c) DNP was discontinued after only a few years of use due to the harmful side effects. Any ideas as to what side effect(s) people who were taking this drug were experiencing? [1] Given E=3 e^-13z ax in free space. What is the associated phasor of the magnetic field?
