3) What's the total energy in the circuit. U=?
4) What is the peak charge on the capacitor. Q0=?
orville walks 318 m due east. He then continues walking along the straight line, but in a different direction, and stops 164 m northeast of his starting point. How far did he walk during the second portion of trip and in what direction.
Speedboat A negotiates a curve whose radius is 118 m. Speedboat B negotiates a curve whose radius is 270 m. Each boat experiences the equivalent centripetal acceleration. What is the ratio vA/vB of the speeds of boats.
A magnetic B field with strength 1 T passes through a metal square loop measuring 0.8 m on its side. If the B field is parallel to the loop's normal
An amount of ideal gas is con?ned to a sealed box at one-half atmospheric pressure, i.e., 50.65 kPa. With clever control, the volume of the box is reduced to 1/8 of its original value (without any gas leaking in or out), while the temperture is ke..
