1) (a) An electron and a proton are eachaccelerated from rest in a uniform electric field of 2.0 ×105 V/m. What are their kinetic energies inJoules after they have each traveled a distance of 0.20 m in the electric field?
(b) What is the ratio of the speeds of theelectron and proton after they have each traveled a distance of0.20 m in the electric field?

2) (a) A 2.0 μF capacitor with aninitial charge Q is discharged through a500 kΩresistor. How much time is required for the charge on the capacitorto decrease to Q/2?
(b) What is the current at the instant whenthe discharging begins?

Potential energy of water were converted to electric energy : Water flows over Victoria Falls, which is 128 m high, at an average rate of 1.20 times 106 kg/s. If two thirds the potential energy of this water were converted to electric energy, how much power would be produced by these falls?

Sharpimage always falls on the sensor : To focus a camera on objects at different distances, the converginglens is moved toward or away from the image sensor, so a sharpimage always falls on the sensor.

Loudspeakers in drawing are producing identical soundwaves : The two loudspeakers in the drawing are producing identical soundwaves. The waves spread out and overlap at thepoint P. This situation is analogous to Young’sdouble-slit experiment, except that sound waves are being used.

An electron and a proton are eachaccelerated from rest : An electron and a proton are eachaccelerated from rest in a uniform electric field of 2.0 ×105 V/m. What are their kinetic energies inJoules after they have each traveled a distance of 0.20 m in the electric field?

Net torque on object instatic equilibrium must be zero : The net torque on an object instatic equilibrium must be zero about any axis. If the net force on a system iszero, then the system must be in static equilibrium. A rotating object must beexperiencing a net torque about the rotation axis.
