Answer:
The Moon blocks the suns light from hitting the surface of the earth
...a nerve. These send signals from the body to the brain and vice versa.
Average speed =
(total distance covered)
divided by
(total time spent covering the distance)
Answer:
Explanation:
First we calculate the energy of the photon
E=(Planck constant × speed of light in vacuum)÷ wave length
E=
Next we find the total energy per second
total energy=
Next we calculate the number the photon per second
= total energy ÷ energy of 1 photon
=
