The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
the energy stored in the capacitor quadruples its original value.
the energy stored in the capacitor doubles its original value.
the energy stored in the capacitor is decreased to one-fourth of its original value.
the energy stored in the capacitor remains constant.
the energy stored in the capacitor is decreased to one-half of its original value.

The ballistic pendulum was invented in 1742 by english mathematician benjamin robins. it consists of an initially stationary pendulum that moves after being struck by a bullet, and it is used to measure the original velocity of the bullet. the known variables are the bullet's mass m, the pendulum's mass m, and the height to which the block and bullet swing, determined by the length of the pendulum l and final angle θ. two principles of physics are necessary to solve for the bullet's original velocity. what are these principles? conservation of momentum and newton's third law conservation of energy and conservation of angular momentum grade summary deductions 0% potential 100% conservation of momentum and newton's second law. newton's second law and conservation of angular momentum. conservation of energy and newton's third law conservation of momentum and conservation of angular momentum. conservation of momentum and conservation of energy conservation of energy and newton's second law.
