What is the answer & show your work please? Assume that a satellite orbits Saturn 250 km above its surface. Given that the mass of Saturn is 5.6846 × 1026 kg, and the radius of Saturn is 6.03 × 107 m, what is the satellite’s period?

The boy of mass 30 kg is at r1= 2 meters from the fulcrum. of the girl is 45 kg, at what r2 must she sit so that they are balanced ?

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Astone is dropped from the upper observation deck of a tower, 250 m above the ground. (assume g = 9.8 m/s2.) (a) find the distance (in meters) of the stone above ground level at time t. h(t) = (b) how long does it take the stone to reach the ground? (round your answer to two decimal places.) s (c) with what velocity does it strike the ground? (round your answer to one decimal place.) m/s (d) if the stone is thrown downward with a speed of 2 m/s, how long does it take to reach the ground? (round your answer to two decimal places.) s
