a). The mass of a gas molecule can be computed from its specific heat at constant volume, cv. Take cv = 0.148 cal/g°C for neon and calculate the mass of a neon atom. (kg)
b). Calculate the molar mass of neon. (g)
Find the speed of a satellite in a circular orbit around the earth with a radius 4.01 times the mean radius of the earth; RE 6.37E+3km; ME 5.98E+24kg
A 7320 kg satellite has an elliptical orbit. The point on the orbit that is farthest from the earth is called the apogee and is at the far right side of the drawing. Find the work done by the gravitational force when the satellite moves from the ap..
