A baseball player applies a force of 200N onto a baseball. Determine the time that baseball player exerts on the baseball if an
2 answers:
Answer:
Time, t = 0.25 seconds
Explanation:
Given that,
Force applied by a baseball player, F = 200 N
We need to find the time that baseball player exerts on the baseball if an impulse of 50 Ns is exerted on the baseball. The impulse exerted on the baseball is given by :
t is time taken
So, the time for which the baseball player exerts on the baseball is 0.25 seconds.

Answer:
Q = 1.2*10⁻¹² C
Explanation:
- For any capacitor, by definition the capacitance C is equal to the relationship between the charge on one of the conductors and the potential difference between them, as follows:
- For the special case of a parallel plate capacitor, just by application of Gauss' law to a rectangular surface half out of the outer surface, and half inside it, it can be showed that the value of the capacitance C is a parameter defined only by geometric constants, as follows:
- So, due to the left sides in (1) and (2) are equal each other, right sides must be equal too.
- Replacing ε₀, εr (dielectric constant), A, d and V by their values, we can solve for Q, as follows:
