The simple pendulum (figure shown in Question 2) consists of a light but rigid bar of length L=0.7 m, with a ball on the end with mass M = 8.1 kg. The pendulum is released from the position shown in dashed lines.
As the pendulum passes through the vertical position with an angular velocity = 19 rad/s, it strikes a sphere of mass m = 1.3 kg, which is initially at rest.
Calculate the angular velocity which the pendulum has immediately after impact if the sphere moves to the left with a velocity v =1 m/s after impact.
Neglect friction, and take counterclockwise rotation as positive.
Your answer should be given with two decimal places, should have the correct sign, and should include the correct units.
A sphere of radius R is uniformly charged to a total charge of Q. It is made to spin about an axis that passes through its center with an angular speed ω. Find the magnitude of the resulting magnetic field at the center of the sphere.
A resistor is in the shape of a cube, with each side of resistance R . Find the equivalent resistance between any two of its adjacent corners.
