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 *

Air initially at 0.75 bar, 1000 k, and occupying a volume of 0.12 m^3 undergoes two processes. process 1-2: the air is compressed isothermally until the volume is halved. process 2-3: the air undergoes a constant pressure process until the volume is halved again. assume ideal gas behavior. a) determine the mass of the air, in kg. b) the work and the heat transfer for each of the two processes, in kj. (100 kj = 1 bar . m^3)

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
