PHYS 1010 Chapter 22: Chapter 22

the masses of the earth and moon are 5.98 * 10^24 and 7.35 * 10^22 kg, respectively. Identical amounts of charge are placed o each body, such that the net force (gravitational plus electrical) on each is zero. What is the magnitude of the charge placed on each body?

24. What does the following program print? int x = 10; void setup() { timesTwo(); println(x); A. 10,20 B. 20, 10 C. 20, 20 void timesTwo() { x = x + 2; println(x);

The moon orbits the earth at a distance of 3.85 x 10^8 m(center of the earth to the center of the moon). The mass of the earth is 5.98 x 10^24 kg, and the mass of the moon is 7.35 x 10^22 kg. What is the moon's orbital period? (Starting with F=ma)
