Answer:
The energy stored is 1.4 x 10^-9 J.
Explanation:
Side of square, L = 10 cm = 0.1 m
Distance, d = 2 mm = 0.002 m
Electric field, E = 4000 V/m
The energy stored in the capacitor is
The capacitance is given by
Answer:
The average velocity of the ball is 1.355 cm/s.
Explanation:
Given;
initial displacement of the ball, x₁ = 8.4 cm
final displacement of the ball, x₂ = 4.2 cm
initial time, t₁ = 3.0 s
final time, t₂ = 6.1 s
The average velocity of the ball is calculated as;
Therefore, the average velocity of the ball is 1.355 cm/s.

The radius of the drop is 0.0006091222 m
Answer:
A very common form of sliding friction is known as kinetic friction. Whenever an object is sliding along a surface, the surface of the two objects creates a force called kinetic friction that opposes the motion of the object.
