If the pressure and temperature of air are 22.6 kpa and -55 °c at an elevation of 10.973 km above the earth's surface, what is the pressure at an elevation of 17.079 km, assuming that the temperature is constant? the molecular weight of air is 28.9 g/mol and the gas constant r is 8.314 j/(mol. k).

not clear

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.
