Answer:
The electric field is 
Explanation:
From the question we are told that
The linear charge density on the inner conductor is 
The linear charge density on the outer conductor is

The position of interest is r = 37.3 mm =0.0373 m
Now this position we are considering is within the outer conductor so the electric field at this point is due to the inner conductor (This is because the charges on the conductor a taken to be on the surface of the conductor according to Gauss Law )
Generally according to Gauss Law

=> 
substituting values


The negative sign tell us that the direction of the electric field is radially inwards
=> 
Answer:
10 kg
Explanation:
The mass of an object does not change even if the amount of gravtiy changes.
so from what i was looking at i think the answer is d because The shorter the wavelength, the higher measure of vitality it produces.So the request is D. Bright beams, Visible light, Infrared, and Microwaves.
Answer:
600
Explanation:
GPE=mgh (mass*gravitational force*height)
m=10 kg
g=10
h=6m
10*10*6= 600 Joules
