Option B is the correct answer.
In a basketball game, a player shoots a jump shot then the floor pushes up on the player.
<h3>Newton's Third Law</h3>
Newton's third law states that when two bodies interact with each other, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction.
In the given situation, a player shoots a jump shot. It means that the player pushes the floor downward direction.
Newton's third law is applicable in this situation where the player pushes the floor downward direction, at the same time the floor pushes the player upward. The amount of force applied to the floor by the player is equal in magnitude and opposite in direction as compared to the force applied to the player by the floor.
Hence the option B is the correct answer.

Answer:
E = 1.711 MeV
Explanation:
From the law of the conservation of energy:
where,
the kinetic energy of positron and electron = 1.2 MeV
Rest energy of the electron and the positron = 0.511 MeV
E = Energy of Photon = ?
Therefore,
<u>E = 1.711 MeV</u>
Answer:
19500kg
Explanation:
If you divide 195000N by 10
Work can be obtained from the following expression
W = F*d
Where F is the force (In this case the force it takes to lift Sarah, which is mass*gravity)
And d is the distance traveled.
W = 60kg*9.8m/s^2 * 4m = 2352 Joules
Answer:
v = 9.45 m/s
Explanation:
given,
mass of the carpenter = 62.5 Kg
length of rope = 13.4 m
Capable of exerting force = 1034 N
centripetal force acting on the body
F =4.664 v² N
Gravitational force on her =
F = m g
F = 62.5 x 9.81
F = 613.125 N
now,
4.664 v² + 613.125 = 1034
4.664 v² = 420.875
v² = 90.24
v = 9.45 m/s
Maximum speed which she can tolerate = v = 9.45 m/s
