Aparallel-plate capacitor is made of two square plates 25 cm on a side and 1.0 mm apart. the capacitor is connected to a 50.0-v battery. with the battery still connected, the plates are pulled apart to a separation of 2.00 mm. what are the energies stored in the capacitor before and after the plates are pulled farther apart? why does the energy decrease even though work is done in separating the plates?

The modern-day generator works on the principle of electromagnetic induction discovered by michael faraday in 1831-32. faraday discovered that the above flow of electric charges could be induced by moving an electrical conductor, such as a wire that contains electric charges, in a magnetic field.

"induction" is the process of charging an object without touching it.hope my answer has you : )

Shy diving is the only sport which doesnot require a high level of physical fitness

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
