Answers

Answer 1

Answer:

organ

Explanation:

The organ removal is the process that involves deep examination. The vital organs may be removed or transplanted if they suffer some sort of disease. The human body has two lungs and two kidneys, if there is a failure or disease in one of these organ the patient can survive without any transplant. In case of heart disease the transplant is the only option that a patient may have. The exact procedure for removal of these organ is determined after deep examination of patient and identifying his history of diseases.

A 2.5-kg object falls vertically downward in a viscous medium at a constant speed of 2.5 m/s. How much work is done by the force the viscous medium exerts on the object as it falls 80 cm?

Answers

Answer:

The workdone is [tex]W_v = - 20 \ J[/tex]

Explanation:

From the question we are told that

    The mass of the object is [tex]m = 2.5 \ kg[/tex]

     The speed of fall is [tex]v = 2.5 \ m/s[/tex]

     The depth of fall is  [tex]d = 80\ cm = 0.8 \ m[/tex]

Generally according to the work energy theorem

      [tex]W = \frac{1}{2} mv_2^2 - \frac{1}{2} mv_1^2[/tex]

Now here given the that the velocity is  constant  i.e  [tex]v_1 = v_2 = v[/tex] then

We have that

    [tex]W = \frac{1}{2} mv^2 - \frac{1}{2} mv^2 = 0 \ J[/tex]  

So in terms of workdone by the potential energy of the object and that of the viscous liquid we have

       [tex]W = W_v - W_p[/tex]

Where  [tex]W_v[/tex] is workdone by viscous liquid

             [tex]W_p[/tex] is the workdone by the object which is mathematically represented as

            [tex]W_p = mgd[/tex]

So  

       [tex]0 = W_v + mgd[/tex]

=>    [tex]W_v = - m * g * d[/tex]

substituting values

       [tex]W_v = - (2.5 * 9.8 * 0.8)[/tex]

      [tex]W_v = - 20 \ J[/tex]

Answers

Answer:

Speed = 20 m/sec at 75 deg South of East = 20 m/sec at 15 deg East of South

Explanation:

given data

truck moves = 25 m/s toward the east.

throws a baseball = 28 m/s southwest

solution

first we take here Speed of truck w.r.to ground i.e. V(p/g) = 25 m/sec toward the east  so we can say

V(p/g) = (25 i) m/sec     ........................1

and

Speed of baseball w.r.t. pickup i.e. V(b/p) = 28 m/sec toward the South West  and   we know that south west direction is in third quadrant

and here both component (x and y) are negative

So  that we can say it

V(b/p) = -28 × cos(45) i - 28 × sin(45) j     =  -19.8 i - 19.8 j  

and

now we use here relative motion  velocity for ball w.r.t ground

V(b/g) = V(b/p) + V(p/g )      ..........................2

put here value and we get

V(b/g) = (-19.8 i - 19.8 j) + 25 i     = 5.2 i - 19.8 j

so

Magnitude of that velocity

| V(b/g) | = [tex]\sqrt{(5.2^2 + 19.8^2)}[/tex]  

| V(b/g) | = 20.47 m/sec

so that  Direction will be here

Direction = arctan (19.8 ÷ 5.2)

Direction = 75.3° South of East

so that

Speed = 20.47 m/sec at 75.3 deg South of East

and 2 significant  

Speed = 20 m/sec at 75 deg South of East = 20 m/sec at 15 deg East of South

The frequency of a physical pendulum comprising a nonuniform rod of mass 1.15 kg pivoted at one end is observed to be 0.658 Hz. The center of mass of the rod is 42.5 cm below the pivot point. What is the rotational inertia of the pendulum around its pivot point

Answers

Answer:

The rotational inertia of the pendulum around its pivot point is [tex]0.280\,kg\cdot m^{2}[/tex].

Explanation:

The angular frequency of a physical pendulum is measured by the following expression:

[tex]\omega = \sqrt{\frac{m\cdot g \cdot d}{I_{o}} }[/tex]

Where:

[tex]\omega[/tex] - Angular frequency, measured in radians per second.

[tex]m[/tex] - Mass of the physical pendulum, measured in kilograms.

[tex]g[/tex] - Gravitational constant, measured in meters per square second.

[tex]d[/tex] - Straight line distance between the center of mass and the pivot point of the pendulum, measured in meters.

[tex]I_{O}[/tex] - Moment of inertia with respect to pivot point, measured in [tex]kg\cdot m^{2}[/tex].

In addition, frequency and angular frequency are both related by the following formula:

[tex]\omega =2\pi\cdot f[/tex]

Where:

[tex]f[/tex] - Frequency, measured in hertz.

If [tex]f = 0.658\,hz[/tex], then angular frequency of the physical pendulum is:

[tex]\omega = 2\pi \cdot (0.658\,hz)[/tex]

[tex]\omega = 4.134\,\frac{rad}{s}[/tex]

From the formula for the physical pendulum's angular frequency, the moment of inertia is therefore cleared:

[tex]\omega^{2} = \frac{m\cdot g \cdot d}{I_{o}}[/tex]

[tex]I_{o} = \frac{m\cdot g \cdot d}{\omega^{2}}[/tex]

Given that [tex]m = 1.15\,kg[/tex], [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], [tex]d = 0.425\,m[/tex] and [tex]\omega = 4.134\,\frac{rad}{s}[/tex], the moment of inertia associated with the physical pendulum is:

[tex]I_{o} = \frac{(1.15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)\cdot (0.425\,m)}{\left(4.134\,\frac{rad}{s} \right)^{2}}[/tex]

[tex]I_{o} = 0.280\,kg\cdot m^{2}[/tex]

The rotational inertia of the pendulum around its pivot point is [tex]0.280\,kg\cdot m^{2}[/tex].

The question is not complete, the value of z is not given.

Assuming the value of z = 4.0m

Answer:

the magnitude of the electric field at any point having z(4.0 m)  =

E = 5.65 N/C

Explanation:

given

σ(surface density) = 0.20 nC/m² = 0.20 × 10⁻⁹C/m²

z = 4.0 m

Recall

E =F/q (coulumb's law)

E = kQ/r²

σ = Q/A

A = 4πr²

∴ The electric field at point z =

I am having trouble because this problem seems to have bothradial and tangential accleration. I tried finding the velocityusing V^2/R, but then that didnt take into account thedeceleration. Any help would be great.

Answers

Answer:

8.7 m/s^2

82.15°

Explanation:

Given:-

- The initial speed of the car, vi = 25 m/s

- The radius of track, r = 129 m

- Car makes a circular " quarter turn "

- The constant tangential acceleration, at = 1.2 m/s^2

Solution:-

- We will solve the problem using rotational kinematics. Determine the initial angular velocity of car ( wi ) as follows:

                          [tex]w_i = \frac{v_i}{r} \\\\w_i = \frac{25}{129}\\\\w_i = 0.19379 \frac{rad}{s}[/tex]

- Now use the constant tangential acceleration ( at ) and determine the constant angular acceleration ( α ) for the rotational motion as follows:

                           at = r*α

                           α = ( 1.2 / 129 )

                           α = 0.00930 rad/s^2

- We know that the angular displacement from the initial entry to the exit of the turn is quarter of a turn. The angular displacement would be ( θ = π/2 ).

- Now we will use the third rotational kinematic equation of motion to determine the angular velocity at the exit of the turn (wf) as follows:

                            [tex]w_f^2 = w_i^2 + 2\alpha*theta\\\\w_f = \sqrt{0.19379^2 + 0.00930\pi } \\\\w_f = 0.25840 \frac{rad}{s}[/tex]

- We will use the evaluated final velocity ( wf ) and determine the corresponding velocity ( vf ) as follows:

                            [tex]v_f = r*w_f\\\\v_f = 129*0.2584\\\\v_f = 33.33380 \frac{x}{y}[/tex]

- Now use the formulation to determine the centripetal acceleration ( ac ) at this point as follows:

                            [tex]a_c = \frac{v_f^2}{r} \\\\a_c = \frac{33.3338^2}{129} \\\\a_c = 8.6135 \frac{m}{s^2}[/tex]

- To determine the magnitude of acceleration we will use find the resultant of the constant tangential acceleration ( at ) and the calculated centripetal acceleration at the exit of turn ( ac ) as follows:

                             [tex]|a| = \sqrt{a^2_t + a_c^2} \\\\|a| = \sqrt{1.2^2 + 8.6135^2} \\\\|a| = 8.7 \frac{m}{s^2}[/tex]

- To determine the angle between the velocity vector and the acceleration vector. We need to recall that the velocity vector only has one component and always tangential to the curved path. Hence, the velocity vector is parallel to the tangential acceleration vector ( at ). We can use the tangential acceleration ( at ) component of acceleration ( a ) and the centripetal acceleration ( ac ) component of the acceleration and apply trigonometric ratio as follows:

                          [tex]q = arctan \frac{a_c}{a_t} = arctan \frac{8.7}{1.2} \\\\q = 82.15 ^.[/tex] 

Answer: The angle ( q ) between acceleration vector ( a ) and the velocity vector ( v ) at the exit of the turn is 82.15° .

Given a double slit apparatus with slit distance 1 mm, what is the theoretical maximum number of bright spots that I would see when I shine light with a wavelength 400 nm on the slits

Answers

Answer:

The maximum number of bright spot is [tex]n_{max} =5001[/tex]

Explanation:

From the question we are told that

     The  slit distance is [tex]d = 1 \ mm = 0.001 \ m[/tex]

      The  wavelength is  [tex]\lambda = 400 \ nm = 400*10^{-9 } \ m[/tex]

       

Generally the condition for interference is  

        [tex]n * \lambda = d * sin \theta[/tex]

Where n is the number of fringe(bright spots) for the number of bright spots to be maximum  [tex]\theta = 90[/tex]

=>     [tex]sin( 90 )= 1[/tex]

So

     [tex]n = \frac{d }{\lambda }[/tex]

substituting values

     [tex]n = \frac{ 1 *10^{-3} }{ 400 *10^{-9} }[/tex]

     [tex]n = 2500[/tex]

given there are two sides when it comes to the double slit apparatus which implies that the fringe would appear on two sides so the maximum number of bright spots is mathematically evaluated as

        [tex]n_{max} = 2 * n + 1[/tex]

The  1  here represented the central bright spot

So  

      [tex]n_{max} = 2 * 2500 + 1[/tex]

     [tex]n_{max} =5001[/tex]      

       

An experimenter finds that standing waves on a string fixed at both ends occur at 24 Hz and 32 Hz , but at no frequencies in between. Part A What is the fundamental frequency

Answers

Answer:

8 Hz

Explanation:

Given that

Standing wave at one end is 24 Hz

Standing wave at the other end is 32 Hz.

Then the frequency of the standing wave mode of a string having a length, l, is usually given as

f(m) = m(v/2L), where in this case, m could be 1. 2. 3. 4 etc

Also, another formula is given as

f(m) = m.f(1), where f(1) is the fundamental frequency..

Thus, we could say that

f(m+1) - f(m) = (m + 1).f(1) - m.f(1) = f(1)

And as such,

f(1) = 32 - 24

f(1) = 8 Hz

Then, the fundamental frequency needed is 8 Hz

A cylinder initially contains 1.5 kg of air at 100 kPa and 17 C. The air is compressed polytropically until the volume is reduced by one-half. The polytropic exponent is 1.3. Determine the work done (absolute value) and heat transfer for this process.

Answers

Answer:

Work done = 96.15 KJ

Heat transferred = 24 KJ

Explanation:

We are given;

Mass of air;m = 1.5 kg

Initial pressure;P1 = 100 KPa

Initial temperature;T1 = 17°C = 273 + 17 K = 290 K

Final volume;V2 = 0.5V1

Since the polytropic exponent is 1.3,thus it means;

P2 = P1[V1/V2]^(1.3)

So,P2 = 100(V1/0.5V1)^(1.3)

P2 = 100(2)^(1.3)

P2 = 246.2 KPa

To find the final temperature, we will make use of combined gas law.

So,

(P1×V1)/T1 = (P2×V2)/T2

T2 = (P2×V2×T1)/(P1×V1)

Plugging in the known values;

T2 = (246.2×0.5V1×290)/(100×V1)

V1 cancels out to give;

T2 = (246.2×0.5×290)/100

T2 = 356.99 K

The boundary work for this polytropic process is given by;

W_b = - ∫P. dv between the initial boundary and final boundary.

Thus,

W_b = - (P2.V2 - P1.V1)/(1 - n) = -mR(T2 - T1)/(1 - n)

R is gas constant for air = 0.28705 KPa.m³/Kg.K

n is the polytropic exponent which is 1.3

Thus;

W_b = -1.5 × 0.28705(356.99 - 290)/(1 - 1.3)

W_b = 96.15 KJ

The formula for the heat transfer is given as;

Q_out = W_b - m.c_v(T2 - T1)

c_v for air = 0.718 KJ/Kg.k

Q_out = 96.15 - (1.5×0.718(356.99 - 290))

Q_out = 24 KJ

    The  distance of the slit separation is  [tex]d = 0.500 \ mm = 5.0 *10^{-4} \ m[/tex]

 

Generally the condition for two slit interference  is  

     [tex]dsin \theta = m \lambda[/tex]

Where m is the order which is given from the question as  m = 2

=>    [tex]\theta = sin ^{-1} [\frac{m \lambda}{d} ][/tex]

 substituting values  

      [tex]\theta = 0.0022 rad[/tex]

Now on the second question  

   The distance of separation of the slit is  

       [tex]d = 0.300 \ mm = 3.0 *10^{-4} \ m[/tex]

The  intensity at the  the angular position in part "a" is mathematically evaluated as

      [tex]I = I_o [\frac{sin \beta}{\beta} ]^2[/tex]

Where  [tex]\beta[/tex] is mathematically evaluated as

       [tex]\beta = \frac{\pi * d * sin(\theta )}{\lambda }[/tex]

  substituting values

     [tex]\beta = \frac{3.142 * 3*10^{-4} * sin(0.0022 )}{550 *10^{-9} }[/tex]

    [tex]\beta = 0.06581[/tex]

So the intensity is  

    [tex]I = I_o [\frac{sin (0.06581)}{0.06581} ]^2[/tex]

   [tex]I = 0.000304 I_o[/tex]

If the frequency of a periodic wave is cut in half while the speed remains the same, what happens to the wavelength

Answers

Answer:

The wavelength becomes twice the original wavelength

Explanation:

Recall that for regular waves, the relationship between wavelength, velocity (i.e speed) and frequency is given by

v = fλ

where,

v = velocity,

f = frequency

λ = wavelength

Before a change was made to the frequency, we have: v₁ = f₁ λ₁

After a change was made to the frequency, we have: v₂ = f₂ λ₂

We are told that the speed remains the same, so

v₁ = v₂

f₁ λ₁ = f₂ λ₂ (rearranging this)

f₁ / f₂ = λ₂/λ₁ --------(1)

we are given that the frequency is cut in half.

f₂ = (1/2) f₁     (rearranging this)

f₁/f₂ = 2 -------------(2)

if we substitute equation (2) into equation (1):

f₁ / f₂ = λ₂/λ₁

2 = λ₂/λ₁

λ₂ = 2λ₁

Hence we can see that the wavelength after the change becomes twice (i.e doubles) the initial wavelength.

Three containers are filled with water to the same height and have the same surface area at the base, but the total weight of water is different for each. Which container has the greatest total force acting on its base

Answers

The container has the greatest total force acting on its base is the conatainer with the greatest total weight.

How to find which container has the greatest total force acting on its base?

For each container, there is a pressure, P acting on its base given by

P = F/A where

F = force on base and A = area of base

Now, since the force on the base is the weight of water acting on the base, W, we have that

P = W/A where w = total weight of water acting on base

Now, for each container, the area of base is the same. So, we have that

P ∝ W

So, we see that the pressure is directly proportional to the weight on the container.

Since pressure is directly proportional to force, we see that the force on the base is directly proportional to the weight of water acting on the base.

So, for the greatest force acting on the base, we would have the greatest total weight of water acting on the base.

So, the container has the greatest total force acting on its base is the conatainer with the greatest total weight.

Cathode ray tubes in old television sets worked by accelerating electrons and then deflecting them with magnetic fields onto a phosphor screen. The magnetic fields were created by coils of wire on either side of the tube carrying large currents. In one such TV set, the phosphor screen is 51.2 cm wide, and is 11.1 cm away from the center of the magnetic deflection coils (that is, the center of the region of magnetic field). The electron beam is first accelerated through a 22,000 V potential difference before it enters the magnetic field region, which is 1.00 cm wide. The field is approximately uniform and perpendicular to the velocity of the electrons. If the field were turned off, the electrons would hit the center of the screen.

From largest to smallest, rank the gravitational force that each planet exerts on the star with mass M. Distances are as follows:_________.a) Planet A is 3d from M b) Planet B is 1d from M c) Planet C is 1d from M d) Planet D is 2d from M e) Planet E is 3d from M

Answers

Answer:

Planet A = planet B > planet D > planet A = planet E

Explanation:

Gravitational force obeys the inverse square law. That is,

Gravitation force F is inversely proportional to the square of the distance between the two masses.

The larger the distance, the weaker the gravitational force F.

From largest to smallest, the rank of gravitational force that each planet exerts on the star with mass M. Distances are as follows:

Planet B, planet C, planet D, planet planet A, planet E.

Planet B and C may experience different the same gravitational force depending on their masses. This is also applicable to planet A and E.

Therefore,

Planet A = planet B > planet D > planet A = planet E

200 J of heat is added to two gases, each in a sealed container. Gas 1 is in a rigid container that does not change volume. Gas 2 expands as it is heated, pushing out a piston that lifts a small weight. Which gas has the greater increase in its thermal energy?Which gas has the greater increase in its thermal energy?Gas 1Gas 2Both gases have the same increase in thermal energy.

Answers

Answer:

Gas 1

Explanation:

The reason for this is that for gases attached to both gases or containers, with a heat of 200 J, the change in volume is only observed in gas 2, whereas the volume of gas 1 is the same as that of gas. Therefore, the internal energy (heat) or thermal energy of the system is not utilized for Gas 1 and hence the absorption and transfer of energy is the same, whereas Gas 2 is propagated by the use of additional heat of heat. Thus there is a large increase in the thermal energy of Gas1.

The average density of the body of a fish is 1080kg/m^3 . To keep from sinking, the fish increases its volume by inflating an internal air bladder, known as a swim bladder, with air.
By what percent must the fish increase its volume to be neutrally buoyant in fresh water? Use 1.28kg/m^3 for the density of air at 20 degrees Celsius. (change in V/V)

Answers

Answer:

Increase of volume (F)  = 8.01%

Explanation:

Given:

Density of fish = 1,080 kg/m³

Density of water = 1,000 kg/m³

density of air = 1.28 kg/m³

Find:

Increase of volume (F)

Computation:

1,080 kg/m³  + [F × 1.28 kg/m³ ] = (1+F) × 1,000 kg/m³  

1,080 + 1.28 F =1,000 F + 1,000

80 = 998.72 F

F = 0.0801 (Approx)

F = 8.01%  (Approx)

g The radius of a spherical ball increases at a rate of 3 m/s. At what rate is the volume changing when the radius is equal to 2 meters

Answers

Answer:

dV/dt = 150.79 m^3/s

Explanation:

In order to calculate the rate of change of the volume, you calculate the derivative, respect to the radius of the sphere, of the volume of the sphere, as follow:

[tex]\frac{dV}{dt}=\frac{d}{dt}(\frac{4}{3}\pi r^3)[/tex]                     (1)

r: radius of the sphere

You calculate the derivative of the equation (1):

[tex]\frac{dV}{dt}=\frac{d}{dt}(\frac{4}{3}\pi r^3)=3\frac{4}{3}\pi r^2\frac{dr}{dt}=4\pi r^2\frac{dr}{dt}\\\\\frac{dV}{dt}=4\pi r^2\frac{dr}{dt}[/tex](2)

where dr/dt = 3m/s

You replace the values of dr/dt and r=2m in the equation (2):

[tex]\frac{dV}{dt}=4\pi (2m)^2(3\frac{m}{s})=150.79\frac{m^3}{s}[/tex]

The rate of change of the sphere, when it has a radius of 2m, is 150.79m^3/s

Determine the minimum gauge pressure needed in the water pipe leading into a building if water is to come out of a faucet on the fourteenth floor, 43

Answers

Answer:

The  gauge pressure is  [tex]P = 4.2*10^{5} \ N/m^2[/tex]

Explanation:

From the question we are told that

     The height of the 14th floor from the point where the water entered the building  is  h = 43 m

   

The  gauge pressure is  mathematically represented as

           [tex]P = mgh[/tex]

Where  the m is the mass of the water which is  mathematically represented as  

      [tex]m = \frac{\rho}{V}[/tex]

Where  [tex]\rho[/tex] is the density of the water which has a constant value of  [tex]\rho = 1000 \ kg/m^3[/tex] and this standard value of density the volume is  [tex]1 m^3[/tex] so

     [tex]m = \frac{1000}{1}[/tex]

     [tex]m = 1000 \ kg[/tex]

Thus  

     [tex]P = 1000 * 9.8 * 43[/tex]

     [tex]P = 4.2*10^{5} \ N/m^2[/tex]
