Apoint charge of 8.0 c is placed 0.050 m from a rod that has an electric field of 1.5 × 103 n/c. what is the electric potential energy of the point charge? 6.0 × 10-4 j 2.4 × 10-1 j 6.0 × 102 j 2.4 × 105 j

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.

Ahypothesis is? close agreement by competent observers of observations of the same phenomena. a guess that has been tested over and over again and always found to be true. an educated guess that has yet to be proven by experiment. the long side of a right triangle. a synthesis of a large collection of information that includes guesses.
