Amoon of radius, r moon is orbiting a planet which has a radius, rplanet. given rplanet plus the radius and the period of the moon’s circular orbit, it is posible to calculate

1)acceleration of gravity at the surface of both the moon and the planet and the centripetal of the moon at its location

2)acceleration of gravity at the surface of both the moon and the planet

3)acceleration of gravity at the surface of the planet and the centripetal acceleration of the moon at its location

4)acceleration of gravity at the surface of the moon and the centripetal acceleration of the moon at its location

5)acceleration of gravity at the surface of the planet

6)acceleration of gravity at the surface of the moon

7)centripetal acceleration of the moon at its location

Need in all of themmm only answer if you know plsssss

Acave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. the lift is performed in three stages, each requiring a vertical distance of 10.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?

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
