The wavelength of a particular color of yellow light is 590 nm. The frequency of this color is Sec-I (1 nm 109 m)

Answers

Answer 1

If you would like to know the frequency of yellow light with a wavelength of 590 nm, the following formula can be used: Frequency (ν) = Speed of light (c) / Wavelength (λ).

First, we need to convert the wavelength from nanometers (nm) to meters (m), i.e., 1 nm = 1 x 10^(-9) m.

So, 590 nm = 590 x 10^(-9) m.

Now, we can calculate the frequency using the speed of light (c), which is approximately 3 x 10^8 m/s.

Frequency (ν) = (3 x 10^8 m/s) / (590 x 10^(-9) m).

Frequency (ν) ≈ 5.08 x 10^14 Hz.

Therefore, the frequency of this particular yellow light with a wavelength of 590 nm is approximately 5.08 x 10^14 Hz.

A string is 50.0cm long and has a mass of 3.00g. A wave travels at 5.00m/s along this string. A second string has the same length, but half the mass of the first. If the two strings are under the same tension, what is the speed of a wave along the second string?

Answers

The speed of a wave along the second string is given by the expression √[(2 ˣ  T) / μ1], where T is the tension in the strings and μ1 is the linear mass density of the first string.

What is the speed of a wave along the second string if it has the same length but half the mass of the first string, and both strings are under the same tension?

To find the speed of a wave along the second string, we can use the equation v = √(T/μ), where v is the wave speed, T is the tension in the string, and μ is the linear mass density of the string.

Given that the first string has a length of 50.0 cm and a mass of 3.00 g, we can calculate its linear mass density:

μ1 = mass/length = 3.00 g / 50.0 cm

Now, since the second string has half the mass of the first but the same length, its linear mass density will be:

μ2 = (1/2) ˣ μ1

Since both strings are under the same tension, we can assume the tension is constant, denoted as T.

Now, let's calculate the wave speed along the second string:

v2 = √(T/μ2)Substituting the expression for μ2:v2 = √(T / [(1/2) ˣ μ1])Simplifying further:v2 = √[(2 * T) / μ1]

Therefore, the speed of a wave along the second string is given by √[(2 ˣ T) / μ1], where T is the tension in the strings and μ1 is the linear mass density of the first string.

Tennis ball of mass m= 0.060 kg and speed v = 25 m/s strikes a wall at a 45 degree angle and rebounds with the same speed at 45 degree. what is the impulse ( magnitude and direction) given to the ball?

Answers

The impulse given to the ball has a magnitude of 3 kg*m/s, and a direction of 180 degrees.

The impulse given to an object is equal to the change in momentum of the object. Therefore, we can find the impulse given to the tennis ball by calculating its initial momentum and final momentum, and then finding the difference.

The initial momentum of the ball is:

p1 = m * v = 0.060 kg * 25 m/s = 1.5 kg*m/s

Since the ball rebounds with the same speed and angle, the final momentum of the ball is equal in magnitude and opposite in direction to the initial momentum.

Therefore, the final momentum is:

p2 = -m * v = -0.060 kg * 25 m/s = -1.5 kg*m/s

The change in momentum, and thus the impulse given to the ball, is:

Δp = p2 - p1 = (-1.5 kg*m/s) - (1.5 kg*m/s) = -3 kg*m/s

The impulse is in the opposite direction to the initial momentum, since the ball rebounds in the opposite direction. Therefore, the direction of the impulse is 180 degrees, or opposite to the direction of the initial momentum.

So the impulse given to the ball has a magnitude of 3 kg*m/s, and a direction of 180 degrees.

Answers

The proton needs to be fired toward the lead target with an initial kinetic energy of 25.2 MeV.

What is the initial kinetic energy?

To impact a lead of accelerators nucleus with 20 MeV of kinetic energy, a proton must be fired at the nucleus with a specific amount of initial kinetic energy. In this case, the required initial kinetic energy is 25.2 MeV.

To understand why this is the case, it's important to consider the nature of the nuclear reactions that occur when a proton impacts a nucleus. In order for the proton to penetrate the nucleus, it must have enough kinetic energy to overcome the electrostatic repulsion between the positively charged proton and the positively charged nucleus. This kinetic energy is determined by the velocity of the proton as it approaches the nucleus.

The specific amount of initial kinetic energy required to achieve the desired kinetic energy of the proton upon impact depends on a number of factors, including the mass of the target nucleus and the desired kinetic energy of the proton upon impact.

In this case, the 207 Pb nucleus is relatively heavy, which means that the proton must be fired with a higher initial kinetic energy in order to achieve the desired kinetic energy upon impact. The exact value of 25.2 MeV is calculated based on the mass of the lead nucleus and the desired kinetic energy of the proton upon impact.

The distance between the watch and the magnifier is 11.9 cm and the angular magnification of the engraving is 2.87.

What is the distance between the watch and the magnifier, and what is the angular magnification of the engraving?

To find the distance between the watch and the magnifier, we can use the thin lens formula:

1/f = 1/di + 1/do

where f is the focal length of the magnifier, di is the distance of the image from the magnifier (which is the engraver's near point of 25.4 cm), and do is the distance between the watch and the magnifier (which we want to find).

Rearranging the formula, we get:

1/do = 1/f - 1/di

Substituting the given values, we get:

1/do = 1/0.0885 m - 1/0.254 m

Solving for do, we get:

do = 0.119 m or 11.9 cm

Therefore, the distance between the watch and the magnifier is 11.9 cm.

And find the angular magnification of the engraving, we can use the formula:

M = di / f

where di is the distance of the image from the magnifier (which is the engraver's near point of 25.4 cm) and f is the focal length of the magnifier.

Substituting the given values, we get:

M = 0.254 m / 0.0885 m

a helium balloon is filled to a volume of 27.7 l at 300 k. (ch. 10) what will the volume of the balloon (in l) become if the balloon is heated to raise the temperature to 392 k?

Answers

The helium balloon is heated to raise the temperature from 300 K to 392 K, the volume of the balloon will become approximately 36.1 L.

To find the final volume of the helium balloon when the temperature is raised from 300 K to 392 K, we can use the formula from Charles's Law, which states that the volume of a gas is directly proportional to its temperature when the pressure and amount of gas are constant.

The formula for Charles's Law is V1/T1 = V2/T2, where V1 and T1 are the initial volume and temperature, and V2 and T2 are the final volume and temperature.

Given the initial volume (V1) = 27.7 L and the initial temperature (T1) = 300 K, we need to find the final volume (V2) when the temperature (T2) is raised to 392 K.

Using the formula:
(27.7 L) / (300 K) = (V2) / (392 K)

Now, we need to solve for V2:
V2 = (27.7 L) * (392 K) / (300 K)

V2 ≈ 36.1 L

So, when the helium balloon is heated to raise the temperature from 300 K to 392 K, the volume of the balloon will become approximately 36.1 L.

Answers

The force on charge q2 is approximately 179.751 N.

The force between two point charges can be found using Coulomb's law:
F = (k * q1 * q2) / r^2
Where F is the force between the charges, k is the Coulomb constant (8.98755 × 10^9 N·m^2/C^2), q1 and q2 are the magnitudes of the charges in Coulombs, and r is the distance between the charges in meters.
In this case, q1 = 2 µC and q2 = 10 µC. The distance between the charges is the distance between the origin and the point on the x-axis where q2 is located, which is 10 m.
So, we can calculate the force on q2 as follows:
F = (8.98755 × 10^9 N·m^2/C^2) * (2 µC) * (10 µC) / (10 m)^2
F = (8.98755 × 10^9 * 2 * 10) / 100
F = 1.79751 × 10^9 / 100
F = 1.79751 × 10^7 N
The force on charge q2, we can use Coulomb's Law. Coulomb's Law states that the force (F) between two point charges is directly proportional to the product of their charges (q1 and q2) and inversely proportional to the square of the distance (r) between them:
F = k * (q1 * q2) / r^2
In this case, q1 = 2 µC, q2 = 10 µC, r = 10 m, and the Coulomb constant (k) is 8.98755 × 10^9 N·m^2/C^2.
The charges to Coulombs: q1 = 2 × 10^-6 C and q2 = 10 × 10^-6 C.
F = (8.98755 × 10^9 N·m^2/C^2) * ((2 × 10^-6 C) * (10 × 10^-6 C)) / (10 m)^2
F = (8.98755 × 10^9 N·m^2/C^2) * (2 × 10^-5 C^2) / (100 m^2)

Answers

The answer to the question is that the frequency of this particular color of violet light with a wavelength of 430 nm is approximately 6.98 x 10^14 sec^-1.

To find the frequency, we can use the formula for the relationship between wavelength, frequency, and the speed of light (c = λν), where c is the speed of light, λ is the wavelength, and ν is the frequency. The speed of light is approximately 3.00 x 10^8 m/s.

First, convert the wavelength from nanometers to meters (1 nm = 1 x 10^-9 m), so 430 nm is equal to 4.30 x 10^-7 m.

Then, rearrange the formula to solve for frequency (ν = c / λ) and plug in the values: ν = (3.00 x 10^8 m/s) / (4.30 x 10^-7 m) ≈ 6.98 x 10^14 sec^-1.

Answers

The car stereo's sound waves transfer energy to the particles in the window, causing them to vibrate and resulting in the vibrations of the window. This phenomenon demonstrates the interaction between sound waves, particles, vibration, and energy.

When music is played through a car stereo, it generates sound waves that travel through the air as a series of compressions and rarefactions. These sound waves consist of alternating high-pressure regions (compressions) and low-pressure regions (rarefactions). As the sound waves reach the window, they encounter the particles present in the window's material.

The sound waves transfer their energy to these particles as they collide with them. This energy causes the particles to vibrate rapidly. The vibrations of the particles are then transmitted to the window, causing it to vibrate as well. The vibrations in the window create oscillations in the air on the other side of the window, which can be perceived as sound by our ears.

Part A: The auditory canal acts as a resonant tube, and it can resonate at specific frequencies called harmonics. To determine the frequencies of the first two harmonics, we need to consider the length of the auditory canal. Given that the length of the canal is approximately 2.4 cm and the speed of sound in air is 344 m/s, we can use the formula for the fundamental frequency of a closed-closed tube:

f1 = (v / 4L) = (344 m/s / 4 * 0.024 m) ≈ 1433.33 Hz

To find the frequency of the second harmonic, we multiply the fundamental frequency by 2:

f2 = 2 * f1 ≈ 2866.67 Hz

Part B: To find the corresponding sound wavelengths for the first two harmonics, we can use the formula for the wavelength of a sound wave:

λ = v / f

For the first harmonic (f1 ≈ 1433.33 Hz):

λ1 = (344 m/s) / (1433.33 Hz) ≈ 0.240 m ≈ 24.0 cm

Answers

The energy stored in the inductor one time constant after the switch is closed is 79.2 J.  the energy stored in the inductor when the current reaches its maximum value is 316.8 J.


where E is the energy stored in joules, L is the inductance in henries, and I is the current in amperes.
(a) When the current reaches its maximum value, the energy stored in the inductor can be calculated as follows:
The maximum current can be found using Ohm's Law, which states that V = IR, where V is the voltage, I is the current, and R is the resistance. In this case, V = 24 V, R = 2.0 ?, so I = V/R = 12 A.
Using this value of current and the inductance of the inductor, we can calculate the energy stored in the inductor as:
E = (1/2) * L * I^2
E = (1/2) * 4.4 H * (12 A)^2
E = 316.8 J


(b) One time constant after the switch is closed, the current in the circuit can be found using the formula:
I = I0 * e^(-t/tau)
where I0 is the initial current, t is the time since the switch was closed, and tau is the time constant, which is given by tau = L/R.
In this case, the time constant can be calculated as:
tau = L/R = 4.4 H / 2.0 ?
tau = 2.2 s
One time constant after the switch is closed, t = 2.2 s, and the current can be found as:
I = I0 * e^(-t/tau)
I = 12 A * e^(-2.2 s / 2.2 s)

Answers

A copper kettle contains water at 24 8c. When the water is heated to its boiling point of 100.0 8c, the volume of the kettle expands by 1.2 x 10^25 m³. The volume of the kettle at 24°C is approximately 1.1998 x 10^25 m³.

To determine the volume of the kettle at 24°C, we can use the formula for volume expansion:
ΔV = βV₀ΔT
Where ΔV is the change in volume, β is the coefficient of volume expansion for copper, V₀ is the initial volume at 24°C, and ΔT is the change in temperature.
Given that the kettle expands by 1.2 x 10^25 m³ when heated from 24°C to 100°C, we can find the initial volume (V₀) as follows:
1.2 x 10^25 = βV₀(100 - 24)
Assuming β for copper is 5.0 x 10^-5 K^-1:
1.2 x 10^25 = (5.0 x 10^-5)(V₀)(76)
Solving for V₀:

what is the number of the highest harmonic that may be heard by a person who can hear frequencies from 20 hz to 20000 hz?

Answers

The highest harmonic that may be heard by a person who can hear frequencies from 20 Hz to 20,000 Hz is the 100th harmonic (H₁₀₀).

The human auditory system can perceive sounds within a frequency range of 20 Hz to 20,000 Hz. The fundamental frequency (first harmonic) is the lowest frequency that can be heard, and the highest frequency that can be perceived is determined by the limit of human hearing.

Harmonics are multiples of the fundamental frequency, and their frequency values increase with each multiple. Therefore, the frequency of the nth harmonic is given by n times the fundamental frequency.

To determine the highest harmonic that can be heard, we need to find the harmonic whose frequency is closest to the upper limit of human hearing, which is 20,000 Hz.

Setting n times the fundamental frequency equal to 20,000 Hz, we get:

n × 20 Hz = 20,000 Hz

Solving for n, we get:

n = 20,000 Hz / 20 Hz = 1000

Therefore, the 1000th harmonic can be heard, but it is not audible as a distinct sound because it is too high-pitched. The highest audible harmonic is the 100th harmonic, whose frequency is 100 times the fundamental frequency:

100 × 20 Hz = 2000 Hz

Therefore, the highest harmonic that can be heard by a person with normal hearing is the 100th harmonic (H₁₀₀).

a certain transverse wave is described by y(x,t)=bcos[2π(xl−tτ)], where b = 6.90 mm, l = 30.0 cm, and τ = 3.80×10−2 s.

Answers

The given transverse wave is described by the equation y(x,t)=6.90 mm cos[2π(x(30.0 cm)-t(3.80×10−2 s))] to provide an explanation, this equation represents the displacement of the wave at a certain point (x) and time (t). The displacement is given by wavelength (30.0 cm) and τ is the period (3.80×10−2 s) of the wave.

The argument inside the cosine function represents the phase difference between the wave at two different points in space and time. As the wave propagates, this phase difference changes, causing the wave to oscillate with a certain frequency and wavelength. Overall, the equation y(x,t)=6.90 mm cos[2π(x(30.0 cm)-t(3.80×10−2 s))] describes the displacement of a transverse wave with a wavelength of 30.0 cm and a period of 3.80×10−2 s at a certain point (x) and time (t) transverse wave described by the equation y(x,t) = bcos[2π(x/l - t/τ)], where b = 6.90 mm, l = 30.0 cm, and τ = 3.80×10^-2 s.

Increasing the displacement of a vibrating particle in a mechanical wave from the equilibrium position will increase:

Answers

Increasing the displacement of a vibrating particle in a mechanical wave from the equilibrium position will increase amplitude. The correct option is C.

The amplitude of a mechanical wave increases with the movement of a vibrating particle from its equilibrium point.

The largest distance a particle can travel from its rest position is known as amplitude, which reveals the wave's energy and intensity.

The wave's wavelength, frequency, or phase velocity are unaffected by this amplitude shift.

The wave's strength and total magnitude are therefore improved by raising the particle's displacement without changing the wave's fundamental properties, such as frequency or speed.

Thus, the correct option is C.

a step-up transformer is designed to produce 1840 v from a 115-v ac source. if there are 384 turns on the secondary coil, how many turns should be wound on the primary coil?

Answers

A step-up transformer is designed to produce 1840 v from a 115-v ac source. if there are 384 turns on the secondary coil, the number of turns required on the primary coil of the step-up transformer is 24.

To determine the number of turns required on the primary coil of a step-up transformer, we can use the turns ratio equation:

Turns ratio = (Number of turns on secondary coil) / (Number of turns on primary coil)

Given:

Voltage on the secondary coil ([tex]V_secondary[/tex]) = 1840 V

Voltage on the primary coil ([tex]V_primary[/tex]) = 115 V

Number of turns on the secondary coil ([tex]N_secondary[/tex]) = 384

We need to solve for the number of turns on the primary coil ([tex]N_primary[/tex]).

Using the turns ratio equation:

Turns ratio = [tex]V_secondary[/tex] / [tex]V_primary[/tex] = [tex]N_secondary[/tex] / [tex]N_primary[/tex]

Plugging in the given values:

1840 V / 115 V = 384 / [tex]N_primary[/tex]

Simplifying the equation:

16 = 384 / [tex]N_primary[/tex]

To solve for [tex]N_primary[/tex], we can rearrange the equation:

[tex]N_primary[/tex] = 384 / 16

[tex]N_primary[/tex] = 24

. the fifth root of fifteen is equal to ________. 15 raised to the power of 15 one fifth of 15 15 raised to the power of 1/5 one fifteenth of 15

Answers

The fifth root of fifteen is equal to c. 15 raised to the power of 1/5.

This means that if we take the number 15 and raise it to the power of 1/5, we will get the fifth root of fifteen, to understand this better, let's first look at what a root is. A root is the inverse of a power, for example, if we have 2^3 = 8, the inverse of this operation would be taking the cube root of 8, which gives us 2 as the answer.

In this case, the fifth root of fifteen means we are looking for the number that, when raised to the power of 5, equals 15. So, if we take 15 and raise it to the power of 1/5, we are essentially finding the number that, when multiplied by itself 5 times, equals 15.  Mathematically, we can express this as: (15)^(1/5) = x, where x is the fifth root of fifteen.  Therefore, the answer to the question is: the fifth root of fifteen is equal to c. 15 raised to the power of 1/5.

Jupiter is large, but rotates extremely fast! While we need 24 hours here on Earth to


complete one day, Jupiter's day takes only 9.8 hours. How long to get Jupiter to stop


rotating if its rotation is slowed by an average angular acceleration of -3.0 x 10^-8 rad/s^2?



Show all work, formulas, and units for credit.

Answers

It would take approximately 3.27 million years for Jupiter to come to a complete stop if its rotation is slowed by an average angular acceleration of -3.0 x 10^-8 rad/s^2.

To calculate the time it takes for Jupiter to stop rotating, we can use the formula:

Δt = ωf / α

Where:

Δt is the time taken

ωf is the final angular velocity (0 rad/s, as Jupiter comes to a complete stop)

α is the angular acceleration (-3.0 x 10^-8 rad/s^2)

We know that Jupiter's initial angular velocity is ωi = 2π / T, where T is the duration of Jupiter's day (9.8 hours or 9.8 x 3600 seconds).

Substituting the values into the formula, we have:

Δt = ωf / α

Δt = 0 rad/s / (-3.0 x 10^-8 rad/s^2)

Δt = -1 / (-3.0 x 10^-8) s

Δt ≈ 3.33 x 10^7 s

Converting this to years:

Δt ≈ 3.33 x 10^7 s / (365.25 days/year x 24 hours/day x 3600 s/hour)

Δt ≈ 3.27 x 10^6 years

Therefore, it would take approximately 3.27 million years for Jupiter to come to a complete stop with the given angular acceleration.

A commuter backs her car out of her garage starting from rest with an acceleration of 1. 40m/s2.



How long does it take her to reach a speed of 2. 00 m/s?

Answers

It takes her approximately 1.43 seconds to reach a speed of 2.00 m/s. The calculation is done using the equation v = u + at, where v is the final velocity (2.00 m/s), u is the initial velocity (0 m/s), a is the acceleration (1.40 m/s²), and t is the time taken.

Given that the initial velocity (u) is 0 m/s and the acceleration (a) is 1.40 m/s², we can use the equation v = u + at to find the time taken (t) to reach a speed of 2.00 m/s.

2.00 m/s = 0 m/s + (1.40 m/s²) * t

Simplifying the equation:

2.00 m/s = 1.40 m/s² * t

Dividing both sides of the equation by 1.40 m/s²:

t = 2.00 m/s / 1.40 m/s² ≈ 1.43 seconds

Therefore, it takes approximately 1.43 seconds for the commuter to reach a speed of 2.00 m/s.

a motor designed to operate on 120v draws a current of 33a when it first starts up. at its normal operating speed, the motor draws a current of 2.7a. what is the back emf at normal operating speed?

Answers

The back emf at normal operating speed is 110.19V.The back emf (electromotive force) is a voltage that is generated by a motor when it is running.

It opposes the applied voltage and reduces the current flowing through the motor. The relationship between back emf, applied voltage, and current is given by the equation: Back emf = Applied voltage - (Current x Resistance)

We can rearrange this equation to solve for the back emf: Back emf = Applied voltage - (Current x Resistance). At start-up, the current drawn by the motor is 33A. We can use Ohm's Law to calculate the resistance of the motor: Resistance = Applied voltage / Current, Resistance = 120V / 33A, Resistance = 3.64 ohms

Now we can calculate the back emf at normal operating speed, where the current drawn by the motor is 2.7A: Back emf = 120V - (2.7A x 3.64 ohms), Back emf = 110.19V

Therefore, the back emf at normal operating speed is 110.19V.

A long, hollow wire has inner radius R1 and outer radius R2. The wire carries current I uniformly distributed across the area of the wire.a) Use Ampere's law to find an expression for the magnetic field strength in the region 0

Answers

The magnetic field strength B in the region 0 < r < R1 is B = (μ₀I * r) / (2π * (R2² - R1²)), and in the region R1 < r < R2 is B = (μ₀I * (R2² - r²)) / (2π * r * (R2² - R1²)).

To find the magnetic field strength, we can use Ampere's law, which states that the line integral of the magnetic field B around a closed loop equals μ₀ times the current enclosed by the loop.

For the region 0 < r < R1, consider a circular Amperian loop of radius r inside the wire.

Applying Ampere's law and solving for B, we obtain B = (μ₀I * r) / (2π * (R2² - R1²)).

For the region R1 < r < R2, consider a circular Amperian loop of radius r that encloses the entire inner radius.
