Consider a horizontal floor without friction. Then a person of weight 900N pushes horizontally with a force of 200 N on a crate weighing 1800 N. Which statement could be true as a result of this push? a. The crate will not move because the push is less than its weight.
b. The person will accelerate at 1.08 m/s^2 and the crate will accelerate at 2.17 m/s^2, but in opposite directions.
c. The person and crate will both have an acceleration of 1.08 m/s^2, but in opposite directions.
d. The person and crate will both have an acceleration of 2.17 m/s^2, but in opposite directions.
e. The person will accelerate at 2.17 m/s2 and the crate will accelerate at 1.08 m/s^2, but in opposite directions.

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

Selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
