Explanation:
Given that,
Magnitude of electric field in +x direction, E = 4.9 V/m
Part A :
The relation between electric and magnetic field is given by :
c is the speed of light
So, the magnetic field of the wave at this same point in space and instant in time is .\
Part B :
The direction of electric and magnetic field is same i.e. +x direction.
Hence, this is the required solution.

Answer:
45.9m
Explanation:
Given parameters:
Final velocity = 30m/s
Initial velocity = 0m/s
Unknown:
Height of fall = ?
Solution:
The motion equation to solve this problem is given below;
V² = U² + 2gH
V² = 0 + (2 x 9.8 x H)
30² = 19.6H
H = = 45.9m
The right answer for the question that is being asked and shown above is that: "all of the above." the following that can be determined by studying the spectrum of a star includes: the chemicals in the atmosphere of the star; the motion of the star; <span>the temperature of the atmosphere of the star.</span>
a. θ = 41. 4°
b. θ = 60°
c. θ = 75. 5°
d. θ = 90°
<h3>How to determine the angle</h3>
From the given information, we would be using the Malus' law
It is given as;
I = I0 cos²θ
Where I0 is the intensity of the polarized light after passing through P
a. To find the angle, compare with the given equation
I = (0.750)I0
I = I0 cos θ
then
cos θ = 0. 750
θ =
θ = 41. 4°
b. I = (0.500)I0
cos θ = 0. 500
θ =
θ = 60°
c. I = (0.250)I0
cos θ = 0. 250
θ =
θ = 75. 5°
d. I = 0
cos θ = 0
θ =
θ = 90°
