Sound waves travel faster through liquids than solids because the particles are more spread out. answer true false

What is the radius of the circular path ofa charged particle in a magnetic field?

Explain earth's motion, using the terms "precession" and "rotation" in your answer.

(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.)
