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:
The radius r of the metal sphere.
Explanation:
From Gauss's law we know that for a spherical charge distribution with charge 
, the electrical field at distance 
from the center of the sphere is given by
What is important to notice here is that the radius of the sphere does not matter because any test charge sitting at distance feels the force as if all the charge were sitting at the center of the sphere.
This situation is analogous to the gravitational field. When calculating gravitational force due to a body like the sun or the earth, we take not of only the mass of the sun and the distance from it's center; the sun's radius does not matter because we assume all of its mass to be concentrated at the center.
Answer:
Energy stored in inductor will be 20.797 J
Explanation:
We have given inductance L = 3.54 H
And resistance R = 7.76 ohm
Battery voltage V = 26.6 VOLT
After very long time means at steady state inductor behaves as short circuit
So current 
Now energy stored in inductor 
So energy stored in inductor will be 20.797 J
Fixed shape and fixed volume
Answer:
maximum power = 300 W
Explanation:
Ohm's law: Ohm's law state that the current flowing through a metallic conductor, is directly proportional to the potential difference applied across its end. mathematically it is expressed as,
V = IR............. Equation 1
Where V = potential difference, I = current, R = Resistance of the conductor.
If the power flowing through is gives as
W = 120I - 12I² ..................... Equation 2
To get the maximum power we differentiate of equation 2 and equate to zero
dW/dt = 0
120 - 24l = 0........................... equation 3
Making I the subject of the equation,
I = 120/24 = 5 A.
Suubstituting the value of I into Equation 2
W = 120 (5) - 12(5)²
W = 600 - 300
W = 300 W.
Therefore maximum power = 300 W
