Answer:
0.94m/s (squared)
Explanation:
a=change in velocity/time
a=v-u/t
a=32-0=32/32
a=0.94m/s (squared)
Newton's Third Law of Motion states that for every action there must exist an equal but opposite reaction.
This ultimately implies that, Newton's Third Law of Motion is a law based on action-reaction force pairs.
In this exercise, you're required to identify the action-reaction forces in the attached picture.
Under condition A, a boy is leaning against a wall;
- The force being exerted by the boy on the wall is a force of action.
- The force being exerted by the wall on the boy is a force of reaction.
Under condition B, a boy is jumping off a diving board.
- The force being exerted by the feet of the boy on the diving board is a force of action.
- The force being exerted by the diving board on the feet of the boy is a force of reaction.
Under condition C, a nail is being hammered into the wall.
- The force being exerted by the hammer on the nail is a force of action.
- The force being exerted by the nail on the hammer is a force of reaction.
Under condition D, a man is walking on a ground (floor).
- The force being exerted by the foot of the man on the ground (floor) is a force of action.
- The force being exerted by the ground (floor) on the foot of the man is a force of reaction.
Under condition E, a boy is holding a ball;
- The force being exerted by the hand of the boy on the ball is a force of action.
- The force being exerted by the ball on the hand of the boy is a force of reaction.

Condition for diffraction
Where
a = Distance between slits
m = Order of the fringes
= Wavelength
= At the angle between the ray of light and the projected distance perpendicular between the two objects
For small angles
Where
Where L is the distance between the slits and Y the length of the light.
Replacing we have
The distance between slits d can be expressed also as 
Where N is the number of the fringes, then
Similarly when there is added a new Fringe we have the change of the distance would be :
Linear distance between fringes is
Therefore the answer is
{Answer}
A- (10kg sphere and 30m)
