Determine the momentum of a helium atom (m = 6.696 x 10-27 kg) if the atom is traveling at 1.03% of the speed of light.

Current enters a circuit at a: 1.positive terminal 2.negative terminal 3.low potential side 4.resistor

(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.)

Which of the following are appropriate acceleration units?
