In the sport of curling, players slide 19-kg pieces of granite called stones on ice toward a target. In a direct hit, as one stone strikes another, the first stone will stop moving. In terms of
conservation of momentum, describe what happens to the second stone.

(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.)

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

What’s #16 asking me and how do i solve it?
