An air-filled parallel plate capacitor is connected to a battery and allowed to cahrge up Now a slab of dielectric materialis placed between the plates of the capacitor while he capacitor is still connected to the battery. After this is done one would find-
A. The voltage across the capacitor has increasedB. The charge on the capapcitor has not changedC. the energy stored in the capacitor has decreasedD. the cahrge on the capacitor has increasedE. None of the above
there is an oscillating simple pendulum slowing down. assuming time starts when the pendulum is released find an
a 2000 lbm automobile is driving down a level road at 70 mph. the engine is disengaged and the automobile is allowed to
You drop a stone down a well that's 9.5m deep. How long until you hear the splash? Assume the speed of sound in air is 343m/s
q1. a hotel elevator ascends 170 m with a maximum speed of 5.9 ms. its acceleration and deceleration both have the
Compare the probabilities for an oscillating particle in its ground state to be found in a small interval of width dx at the center of the well and at the classical turning points.
Atomic physicists usually ignore the effect of gravity within an atom. To see why, we may calculate and compare the magnitude of the ratio of the electrical force and gravitational force, Fe/ Fg, between an electron and a proton separated by a dis..
