A solid disk is being accelerated by the weight of an object suspended from a string wrapped around the disk's periphery. If the string is attached at a smaller radius of the disk, would you expect the linear acceleration of the object to change? Will it increase or decrease if It does change?

Select the word from the list that best fits the definition classification of most stars on the h-r diagram

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

(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.)
