A canister filled with 3.5 mol of single-atom helium gas has a temperature of 300 K. What is the approximate total internal energy of the gas? (Recall that
3
the equation for kinetic energy due to translation in a gas is: nRT; the
2
equation for kinetic energy due to rotation of a molecule in a gas is: nRT; and
R = 8.31 J/(mol-K).)

Which statements describe the movement of ocean currents around the globe? check all that apply. strong winds force warm water to sink to the ocean floor. the coriolis effect causes warm and cold water to mix. cool dense water sinks to the ocean floor. warm water replaces cool surface water. wind blowing parallel to the shore causes upwelling of cool water.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
