A balloon is partially inflated with 6.00 L of hydrogen at sea level, where the atmospheric pressure is 1.00 atm. The balloon ascends to an altitude of 1500 m, where the pressure is 0.80 atm. What is the volume of the balloon at the higher altitude if the temperature of the hydrogen doesn’t change during the ascend?

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
