Calculate the force of gravitational attraction between the EARTH and 2 points a GPS satellite. The satellite is orbits 35,786km above the Earth's surface
(that's the "altitude"). The Earth's radius, R_earth, is 6371000m. WHAT IS
THE SEPARATION DISTANCE, R, BETWEEN THE CENTER OF THE EARTH TO
THE CENTER OF THE SATELLITE? ANSWER MUST BE IN METERS. R_total =
R_earth +R_altitude *

28. a stone is projected at a cliff of height h with an initial speed of 42.0 mls directed at angle θ0 = 60.0° above the horizontal. the stone strikes at a, 5.50 s after launching. find (a) the height h of the cliff, (b) the speed of the stone just before impact at a, and (c) the maximum height h reached above the grou

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Two 1.20-m nonconducting wires meet at a right angle. one segment carries + 2.50 µc of charge distributed uniformly along its length, and the other carries - 2.50 µc distributed uniformly along it, as shown in fig. 21.50. ( a. find the magnitude and direction of the electric field these wires produce at point p, which is 60.0 cm from each wire. ( b. if an electron is released at p, what are the magnitude and direction of the net force that these wires exert on it?
