How does the time at which you see things happen at a baseball game compare to the time when you hear things happen? Explain your answer

A negative charge is placed inside the cavity of a hollow metal solid. The outside of the solid is grounded by connecting a conducting wire between it and the earth.

A 0.8 m length of wire is formed into a single turn, square loop in which there is a current of 12 A. The loop is placed in magnetic field of 0.12 T, which is perpendicular to a normal to the loop plane.

The flywheel of a steam engine runs with a constant angular velocity of 150 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 2.2 h.
