The graph below shows the change in average kinetic energy, as represented by temperature, of a 23 g sample of a substance as energy is added to the substance as heat.

What is the specific heat capacity of the solid?

A. 1.85 × 10³ J/kg•°C
B. 4.0 × 10² J/kg•°C
C. 5.0 × 10² J/kg•°C
D. 1.1 × 10³ J/kg•°C

If you go to a nutrition store and buy a supplement, you can count on the fact that it is pure and safe because supplements are regulated, controlled, and inspected by the fda.

What is tan(61)? а. 1.80 b. 0.49 c. 0.61 d. 0.87

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.)
