7. -1 points SerPOP4 4.P.011.soln My Notes 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 that in Paris. The effect was reversed when the clocks returned to Paris. Suppose you weigh 133 pounds in Paris. How much weight would you personally lose in traveling from Paris, where g = 9.8095 m/s2, to Cayenne, where g = 9.7808 m/s ? lbs

Explanation / Answer

Weight = mass*gravity as this equation clearly shows that weight is a function of gravity. Remember as per standard set by scientist, pound is a unit of mass.

Therefore weight lose = m(g at Paris - g at Cayenne)

133 pounds = 60.32778521 kg

Weight lose = 60.32778521(9.8095 - 9.7808)

Weight lose = 1.731407 Newtons

We need is pounds

Weight lose = 0.38923577 lbs
