Imagine two artificial satellites orbiting earth at the same distance. one satellite has a greater mass than the other one? which of the following would be true about their motion?
a. the satellite with the greater mass is being pulled toward earth w/ less of a force than the other satellite
b. the satellite w/ the greater mass is being pulled toward earth w/ a greater force than the other
c. the two satellites are being pulled equal force by the moon
d. the two satellites are being pulled toward earth w/ equal force
imagine two artificial satellites w/ equal masses orbiting earth. one satellite is orbiting closer to earth than the other satellite. which of the following would be true about their motions?
a. the satellite closer to earth will be pulled toward earth w/ the same gravitational pull as the other satellite
b. the satellite closer to earth will be pulled toward earth w/ less gravitational pull than the other satellite
c. both satellites will be pulled w/ equal force toward the moon
d. the satellite closer to earth will be pulled toward earth w/ more gravitational pull than the other satellite

When applying kirchhoff's rules, one of the essential steps is to mark each resistor with plus and minus signs to label how the electric potential changes from one end of the resistor to the other. the circuit in the drawing contains four resistors, each marked with the associated plus and minus signs. however, one resistor is marked incorrectly. which one is it?

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
