Question #1: Determine the force of gravity that the Sun exerts on Pluto. Refer to the data provided in the table at the end of the test document. Question #2 Determine the height above the Mars' surface where the gravitational field strength is 5.00N/kg. Question #3 What speed will a satellite need in order to orbit the moon (Earth's moon) with a perfectly circular orbit 3.85km above its surface (ignore the effect of gravity from Earth and the Sun to answer this question)
