(a) Calculate the impulse imparted by the glass and the wet clay balls on the wall in terms of m and v. Consider the direction of the initial velocities as positive. Help: Momentum is a vector. Don't forget the directions of the velocities.

(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.)

Explain why electric current cannot exist if a current doesn't have a voltage source.

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
