KE = 1/2mv²
= 1/2(20 kg)(2m/s²)
= 1/2(20)(4)
= 1/2 (80)
KE = 40 J
hope this helps :)
The answer would be Newton’s Second Law
The Photon Sphere is the radius of the orbit.
Answer:
spectrum
Explanation:
The spectrum formed different colors due to refraction of light
Answer:
Resultant force will be 123.57 N
Explanation:
We have given that force in north direction
and force in east direction
which is clearly shown in bellow figure
We have to find the resultant force
Resultant force is given by 
So the resultant force will be 123.527 N
