Answer:
D
Explanation:
The tectonic plates move on the mantle, sort of floating on it as they are part of the crust. When they collide things like mountain ranges form, and big earthquakes happen.
Answer:
Explanation:
First we need to find the capacitance of the capacitor.
The capacitance is given by:
Where is the air permittivity, which is approximately 8.85 * 10^(-12)
The radius is 12/2 = 6 mm = 0.006 m, so the area of the capacitor is:
So the capacitance is:
The time constant of a rc-circuit is given by:
So we have that:

Answer:
clockwise torque is due to weight of the person + weight of the ladder
Explanation:
As we know that the forces that act on the ladder is given as
1) friction force
2) Normal force at the ends of the ladder
3) Weight of the person standing on the ladder
4) Weight of the ladder
So here we know that our reference point is at the bottom position of the ladder
So we will have
Torque due to weight of the person and weight of the ladder is counter balanced by the torque due to normal force and torque due to friction force
So here we have
clockwise torque is due to weight of the person + weight of the ladder
