Work = Force * distance
Work = 40N * 10m
Work = 400N
Light takes 162.1 seconds to travel from Venus to earth.
Explanation:
Speed of light=3 x 10⁸ m/s
distance between Venus and earth =30,220,000 miles=48634375680 m
Now the distance is given by d= v t
d= distance
v= velocity
t= time
48634375680= 3 x 10⁸ t
t=162.1 s
The lasers are made from stacking light waves that add together into a larger wave in a process known as constructive interference. This happens only when waves would meet while they are traveling in the same medium. Constructive interference happens at any part of the medium where two waves moves in the same direction. When these waves would meet, they add up and make a larger wave. It is the interference of at leat two waves which produces a single amplitude where it is equal to the sum of the amplitudes of each wave that interfered. The other type is the destructive intereference where the result is a smaller wave.<span />
Answer:
When the electric force between two charged objects change, the distance between the objects increases in Iicreasing the separation distance between objects and decreases the force of attraction or repulsion between objects.
