A 75.6 kg person stands on a scale in an elevator. What does the scale read (it reads mass units, not weight units) when the elevator is accelerating
How far from Earth must a space probe be along a line toward the Sun so that the Sun's gravitational pull on the probe balances the Earth's pull?
Purpose: In this experiment you will use a current-carrying loop to determine the horizontal component of the earths magnetic field for our locality.
The gravitational force on a body located a distance R from the center of a uniform spherical mass is due solely to the mass lying at distance
