Answer:
The speed of the bob when it passes the lowest point 
Explanation:
Given data
When a pendulum swinging back & forth then at highest point the velocity is zero and lowest point velocity is maximum.
Velocity at lowest point is given by
Therefore the speed of the bob when it passes the lowest point
kinetic energy into potential energy.
when the rocks go down it will be kinetic energy but when the rock reach the bottom of the hill it will be converted into potential energy.
Answer:
Explanation:
The electric field that will balance the weight of the oil drop can be calculated using the following:
electric force, F = e E ( where, e is the charge of an electron and E is the electric field)
weight, W = 2.5 ×10⁻¹⁴ N
e E = W
Substitute the values:
Why does time seem to flow only in one direction? What happens in the gray zone between solid and liquid? Can we find a unified theory of physics?
