A bus completes a trip from City A to City B with an overall average speed of 19 m/s. However, the bus made a rest stop for 15 minutes during the trip which brought the average speed down. Only considering the time that the bus was moving, the average speed of the trip was 22.5 m/s. How far apart are City A and City B?

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.)

Which of the following are considered noble gases? a. bromine b. neon c. argon d. chlorine

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?
