Acapacitor is a circuit component that stores energy and can be charged when current flows through it. a current of 3a flows through a capacitor that has an initial charge of 2î¼c (micro coulombs). after two microseconds, how much is the magnitude of the net electric charge (in î¼c) of the capacitor?

During a medieval siege of a castle, the attacking army uses a trebuchet to hurl heavy stones at the castle walls. if the trebuchet launches the stones with a velocity of at an angle of 50.0°, (a) how long does it take the stone to hit the ground? (b) what is the maximum distance that the trebuchet can be from the castle wall to be in range? (c) how high will the stones go? show all your work.
