HELP ME ASAP I WILL MARK YOU THE BRAINLIEST Which statement about one of Newton's laws of motion is not correct?
1: An object in motion continues in motion unless acted upon by and outside force.
2 :a = f/m
3: For every action there is an equal reaction perpendicular to the direction of the force.
4: The total force on an object is calculated by multiplying its mass times its acceleration.

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

If the work required to stretch a spring 3 ft beyond its natural length is 15 ft-lb, how much work is needed to stretch it 27 in. beyond its natural length?

An electron is ejected into a horizontal uniform e⃗ field at a parallel horizontal velocity of v0. assume the electron's initial position x0, initial velocity v0, time t, magnitude of electric field e, electron's mass m, and the magnitude of the electron's charge |e|. ignore the force that earth exerts on the electron. assume the e⃗ field is in the same direction as the initial velocity. part a define the equation for the electron's velocity. express your answer in terms of the variables v0, |e|, t, e, and m.
