The correct answer is B, electrons emit and absorb energy based on their position around the nucleus.
Answer:
The time that the drop is falling =35.875 s
Explanation:
Using one of newton's equation of motion
g = V-u/t ................ Equation 1
Where V = final velocity, u = initial velocity, g = acceleration due to gravity of the moon, t = time.
<em>Note:</em> for a dropping object, u = 0 m/s
g = V/t.................... Equation 2
making t the subject of equation 2 above
t = V/g................. Equation 3
<em>Given: V= 57.4 m/s, g = 1.6 m/s²</em>
Substituting these values into equation 3
t = 57.4/1.6
t = 35.875 s
t = 35.875 s
The time that the drop is falling = 35.875 s

The answer is that all marine animals feed by seperating food particles from water, known as filter feeding.
snow shoes.
shoes with large areas in contact with the snoow. reduces the pressure on the snow, and alows you to sink less. or to walk on the surface.
