Please help! An object has a charge of 4.5c.
-If you touch it to the ground, will it lose electrons from ground or gain electrons from ground?
-What will be it's charge after its grounded?

Moon effect. some people believe that the moon controls their activities. if the moon moves from being directly on the opposite side of earth from you to being directly overhead, by what percentage does (a) the moon's gravitational pull on you increase and (b) your weight (as measured on a scale) decrease? assume that the earth–moon (center-to-center) distance is 3.82 × 10^8 m, earth's radius is 6.37 × 10^6 m, moon's mass is 7.36 × 10^22 kg, and earth's mass is 5.98 × 10^24 kg.

Who was the first scientist to measure speed as distance over time?
