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

Scientists plan to release a space probe that will enter the atmosphere of a gaseous planet. The temperature of the gaseous plan
ZanzabumX [31]
From my research, the image supports the question. From the graph given, we can construct the equation of the line using the two-point formula. Using the given value of 601 K, we can solve for the missing value of altitude.

y - y1 = [(y2 - y1)/(x2 - x1)](x- x1)
y - 147.52 = [ (567 - 147.54)/(78.11 - 18.4) ](x - 18.4)

Substituting y = 601 to solve for x:
601 - 147.52 = [ (567 - 147.54)/(78.11 - 18.4) ](x - 18.4<span>)
</span>x = 83

Therefore, the probe's instruments will fail at 83 kilometers.

A 1900kg airplane is flying at an altitude of 510 above the ground. What is the gravitational potential energy in Joules?
Natalija [7]

Answer: 9496200 joules

Explanation:

Gravitational potential energy, GPE is the energy possessed by the moving plane since it moves against gravity.

Thus, GPE = Mass m x Acceleration due to gravity g x Height h

Since Mass = 1900kg

g = 9.8m/s^2

h = 510 metres (units of height is metres)

Thus, GPE = 1900kg x 9.8m/s^2 x 510m

GPE = 9496200 joules

Thus, the gravitational potential energy of the airplane is 9496200 joules

An Argon laser (λ = 5.0×102nm) shines down a silica glass fiber-optic cable with index of refraction 1.46. What is the speed of
Yanka [14]

Answer:

The speed of the laser light in the cable, c_f=2.1\times 10^8\ m/s

Explanation:

It is given that,

Wavelength of Argon laser, \lambda=5\times 10^2\ nm=5\times 10^{-7}\ m

Refractive index, n = 1.46

Let c_f is the speed of the laser light in the cable. The speed of light in a medium is given by :

c_f=\dfrac{c}{n}

c_f=\dfrac{3\times 10^8\ m/s}{1.46}

c_f=2.05\times 10^8\ m/s

or

c_f=2.1\times 10^8\ m/s

So, the speed of the laser light is 2.1\times 10^8\ m/s. Hence, this is the required solution.
