Several charges in the neighborhood of point p produce an electric potential of 6.0 kv (relative to zero at infinity) and an electric field of 36i n/c at point p. determine the work required of an external agent to move a 3.0-μc charge along the x axis from infinity to point p without any net change in the kinetic energy of the particle.

According to the law of conservation of mass, in a chemical reaction the total starting mass of all the reactants equal the total final mass of all the products. true or false?

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.

While the change in blank will remain the same during a collision, the force needed to bring an object to a stop can be blank if the time if collision is blank
