A race car travels on a curve with 60 mi/hr and radius of curve is 140m. What is the centripetal acceleration?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

Achlorine atom has 17 protons and 18 neutrons. what is its mass number? what is its atomic number?
