Scientists have sent an unmanned space vehicle to Mars to investigate the properties of the planet. Mars' gravitational field is 38% the strength of Earth's gravitational field. How will the weight and mass of the vehicle change on Mars? A) The mass will increase, the weight will increase
B) The mass will decrease, the weight will decrease
C) The mass will remain the same, the weight will decrease
D) The mass will increase, the weight will remain the same

i believe it is C).

C because the mass doesn't change, the vehicle doesn't shrink, but the weight decreases.

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
