The gravitational potential difference between the surface of a planet and a point P, 10 m above the surface, is 8.0 J kg-1. Assuming a uniform field, what is the value of the gravitational field strength in the region between the planets surface and P?
Two objects of equal mass m are separated by a distance r. Which expression gives the gravitational potential at the point P mid way between the two objects? The answer shows as -4Gm/r, but I can't see where this comes from.
A block weighing 6.8 N requires a force of 2.5 N to push it along at constant velocity. What is the coeﬃcient of friction for the surface? A weight W is now placed on the block and 4.6 N is needed to push them both at constant velocity. What is the weight W of
When an electric discharge is passed through boron trichloride a new compound is formed. what is its simplest formula if on analysis it is shown to contain .0878 g of chlorine and .0131 g of boron?
a 6.54 g sample consisting of a mixture of silver nitrate and sodium nitrate is dissolved in water. this mixture then reacts with barium chloride to for 3.50 g of silver chloride. calculate the percent by mass of silver nitrate in the first mixture
