Q7:The distinction between mass and weight was discovered after Jean Richer transported pendulum clocks from Paris, France, to Cayenne, French Guiana, in 1671. He found that they quite systematically ran slower in Cayenne than in Paris. The effect was reversed when the clocks returned to Paris. How much weight would a kg person lose in traveling from Paris, where g =9.8095 m/s^2, to Cayenne, where g= m/s^2? (We will consider how the free-fall acceleration influences the period of a pendulum in Section 15.5.)
