Use the following formula for the electric field strength between two parallel plates:
E = V/d
where,
V: potential difference = 25V
d: distance between plates = 5 cm = 0.05 m
Replace the previous values of the parameters into the formula for E:

Hence, the electric field strength is 500V/m
Answer:
The length of the pendulum is 2.954 m.
Explanation:
Given;
period of the pendulum, T = 3.45 s
The period of the pendulum oscillation is given as;

where;
L is length of the pendulum
g is acceleration due to gravity on Earth = 9.8 m/s²

Therefore, the length of the pendulum is 2.954 m.

Hmm not sure that math is correct but we must remember that energy is never destroyed just transferred. E.g light energy is transferred into heat. So when looking at a car we have
1.friction energy. This is the car running alone the road and wind.
2. Kentic energy. This is the car moving.
3.heat energy. When petrol combust it produces heat energy.
