Move the slider in the variable resistor and see if the voltage displayed in the voltmeter changes. Notice that as you move the slider to the other end of the resistor, the voltage across the variable resistor increases. Now you are ready to make measurements of voltages for different lengths. 1. Measure the power supply voltage using the voltmeter to three decimal places. V0

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

An object has a weight of 500 on earth what is the mass of this object

(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.)
