Suppose an object is located in deep space, far away from any gravity. Would a force need to be applied in order to accelerate the object in space, or would there be no need for a force to make it accelerate?

What are the factors that affect the resistance of a wire?

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

What is the magnitude of the gravitational force acting on the earth due to the sun?
