Amoving particle encounters an external electric field that decreases its kinetic energy from 9970 ev to 6340 ev as the particle moves from position a to position b the electric potential at a is 55.0 v and that at b is 19.0 v determine the charge of the particle include the algebraic sign or with your answer

Why are graphs useful when interpreting data

In automobile steering wheel is shown what is the ideal mechanical advantage blank? if the ama is eight what is the efficiency of the steering wheel?

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.
