An electron is released from rest in a region of space with a nonzero electric field. As the electron moves, does the electric potential energy of the system increase, decrease, or stay the same? increase decrease stay the same

What are the greenhouse gases product bycombustion

The primary of a step-up transformer is connected across the terminals of a standard wall socket, and resistor 1 with a resistance r1 is connected across the secondary. the current in the resistor is then measured.

Block 1 and Block 2 have the same mass, m, and are released from the top of two inclined planes of the same height making 30 degree and 60 degree angles with the horizontal direction, respectively.

Water waves change direction when they encounter water of different depths and begin to move at different wave speeds. This is called A. reflection B. constructive interference C. the Doppler effect D. refraction

What does Newton's second law of motion say

Two sinusoidal waves are moving through a medium in the positive x-direction, both having amplitudes of 7.00 cm, a wave number of k=3.00m-1, an angular frequency of ω=2.50s-1, and a period of 6.00 s, but one has a phase shift of an angle ϕ=π12rad.
