If the detector readings are proportional to the amplitude of the microwave E field, the data from the first polarization experi
ololo11 [35]

Answer:

Fields and variables are proportional

Explanation:

To solve the problem we must first identify the Vector Intensity,

The intensity is given by:

I = I_ {0} cos^2 (\theta)

We also know that the change given by the Intensity is always the square of the amplitude,

This is,

I = A ^ 2

The intensity is <em>proportional</em> to the change exerted on cos ^ 2 (\theta)

That is to say that in turn the amplitus is <em>proportional</em> to the Intensity.

On the other hand, relating the two variables we have

A ^ 2 = A ^ 2_ {0} cos ^ 2 \theta

A = A_ {0} cos \theta

In this way we can conclude that the electric field of intensity is also <em>proportional</em> to cos ^ 2 \theta

Uma massa de 500 Kg desloca-se com velocidade 58 km por hora. Calcule o módulo de sua quantidade por movimento
Simora [160]

The momentum of the object is 8050 kg m/s

Explanation:

The momentum of an object is defined as

p=mv

where

p is the momentum

m is the mass

v is the velocity of the object

For the object in this problem, we have

m = 500 kg is its mass

v = 58 km/h is its velocity

Converting the velocity into m/s,

v=58 \frac{km}{h}\cdot \frac{1000 m/km}{3600 s/h}=16.1 m/s

Therefore now we can find the momentum of the object:

p=(500)(16.1)=8050 kg m/s

A car traveling at 7.3 m/s accelerates at the rate of 0.82 m/s2 for an interval of 7.4 s. Find vf.
MArishka [77]
<h2>Final velocity is 13.37 m/s</h2>

Explanation:

We have equation of motion v = u + at

     Initial velocity, u = 7.3 m/s

     Final velocity, v = ?

     Time, t = 7.4 s

     Acceleration,a = 0.82 m/s²

     Substituting

                      v = u + at  

                      v = 7.3 + 0.82 x 7.4

                      v = 13.368 m/s

Final velocity is 13.37 m/s

A Parachutist with a camera, with descending at a speed of 12.5m/s, releases, the camera at an altitude of 64.3m. What is the ma
jonny [76]

Given :

Initial velocity, u = 12.5 m/s.

Height of camera, h = 64.3 m.

Acceleration due to gravity, g = 9.8 m/s².

To Find :

How long does it take the camera to reach the ground.

Solution :

By equation of motion :

h = ut+\dfrac{gt^2}{2}

Putting all given values, we get :

12.5t+\dfrac{9.8t^2}{2}=64.3\\\\4.9t^2+12.5t=64.3

t = 2.56  and t = −5.116.

Since, time cannot be negative.

t = 2.56 s.

Therefore, time taken is 2.56 s.

Hence, this is the required solution.
