A baseball bat hits a baseball with a force of 100 newtons. What is the force and its direction exerted by the ball on the bat?
1 answer:
Answer:
The force exerted by the ball on the bat has a magnitude of 100 N and its direction is exactly opposite to that of the force exerted by the bat on the ball.
Explanation:
Recall that Newton's third law tells us that : "For every action, there is an equal and opposite reaction."
Therefore if the bat acts on the ball with a force of 100 N, the ball acts on the bat with a similar magnitude of force (100 N) but direction opposite to the original force.

Answer:
6.48*10⁻⁷ C
Explanation:
- By definition, the capacitance of a capacitor is expressed as follows:
- where Q is the charge on one of the plates of the capacitor, and V the potential difference between the plates.
- The maximum electric field, the potential difference, and the distance between plates are related by the following expression:
- Replacing by the givens, we can find V as follows:
- Now, we can find the maximum charge Qmax, as follows:
- The maximum charge that the capacitor can hold is 6.48*10⁻⁷ C.
