Calculate the specific enthalpy of helium at 300 k and 1 atm and the rate at which enthalpy is transported by a stream of helium at the same conditions with a molar flowrate of 300 kmol/h. the specific internal energy of helium at 300 k and 1 atm is 3800 j/mol and specific molar volume is 24.63 l/mol.

Asmall, positively charged ball is moved close to a large, positively charged ball. which describes how the small ball likely responds when it is released? it will move toward the large ball because like charges repel. it will move toward the large ball because like charges attract. it will move away from the large ball because like charges repel. it will move away from the large ball because like charges attract.

You are traveling in a car going at a constant speed of 100km/h down a long, straight highway. you pass another car going in the same direction which is traveling at a constant speed of 80km/h. as measured from your car's reference frame this other car is traveling at −20km/h. what is the acceleration of your car as measured from the other car's reference frame? what is the acceleration of the other car as measured from your car's reference frame?

What are two different ways you could find the value of a? explain these methods.
