D. According to the hierarchy of needs the body and mind must be taken care of first and foremost.
In order to describe motion along a straight line, you must state the speed and direction of the motion. Those two quantities, together, comprise what's known as "velocity".
Answer:
The Short Answer: Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Explanation:
Explanation:
It is given that,
Power of EM waves, P = 1800 W
We need to find the intensity at a distance of 5 m. Also, the rms value of the electric field.
Intensity,
The formula that is used to find the rms value of the electric field is as follows :
c is speed of light and 
is permittivity of free space
So,
Hence, this is the required solution.
use F = ma
F : force m : mass a : acceleration
so
f = 5kg * 20 m/s2 = 100 N
