Aproton accelerates from rest in a uniform electric field of 680 n/c. at one later moment, its speed is 1.30 mm/s (nonrelativistic because v is much less than the speed of light). (a) find the acceleration of the proton.

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the

Positrons are spontaneously emitted from the nuclei of

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
