What is the best way to determine levelness?

A. See if the Acceleration versus Time for both directions are both zero.

B. Plot the Acceleration versus Time for one direction and acceleration should be zero.

C. Plot Position versus Time and compare the linear fit from each direction of travel; slopes should be equal.

D. Plot Position versus Time and compare the linear fit from each direction of travel; slopes should be equal but opposite.

E. Plot Velocity versus Time for both directions; slopes should be equal.

F. See if slope of Velocity versus Time for both directions are equal but opposite.

First, launch the video below. you will be asked to use your knowledge of physics to predict the outcome of an experiment. then, close the video window and answer the question at right. you can watch the video again at any point. part a as in the video, we apply a charge +q to the half-shell that carries the electroscope. this time, we also apply a charge –q to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? view available hint(s) as in the video, we apply a charge + to the half-shell that carries the electroscope. this time, we also apply a charge – to the other half-shell. when we bring the two halves together, we observe that the electroscope discharges, just as in the video. what does the electroscope needle do when you separate the two half-shells again? it deflects more than it did at the end of the video. it deflects the same amount as at end of the video. it does not deflect at all. it deflects less than it did at the end of the video. submit

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

The man of mass m1 and the woman of mass m2 are standing on opposite ends of the platform of mass m0 which moves with negligible friction and is initially at rest with s = 0. the man and woman begin to approach each other. derive an expression for the displacement s of the platform when the two meet in terms of the displacement x1 of the man relative to the platform.
