How do you determine the specific heat of a substance? A. Divide the enthalpy change by the change in temperature.
B. Divide the enthalpy change by the product of the mass and change in temperature.
C. Divide the change in temperature by the product of the mass and enthalpy change.
D. Divide the change in temperature by the change in enthalpy.

Consider a small frictionless puck perched at the top of a fixed sphere of radius r. if the puck is given a tiny nudge so that it begins to slide down, through what vertical height will it descend before it leaves the surface of the sphere? [hint: use conservation of energy to find the puck's speed as a func e conservation of energy to find the puck's speed as a function of its height at what value of this normal force does the puck leave the sphere? ] here on the puck.
