Immediately after the switch is closed, determine the value of the charge Q on the capacitor, the voltage Von the capacitor. Also, find the current I through the 20-Ω resistor (R3) that is in parallel with the capacitor. Make sure you clearly explain your reasoning.

If a stone with an original velocity of 0 is falling from a ledgeand takes 8 seconds to hoybthe ground whays the final velocity of the stone

Apulley with mass mp and a radius rp is attached to the ceiling, in a gravity field of 9.81 m/s2 and rotates with no friction about its pivot.

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
