So for problem, I would have to build a series circuit and hook it up to the battery and voltmeter then find the voltage for each of the resistors. As the resistor increases, voltage increases. Therefore, am I suppose to look at the unknown resistor's voltage and see how it compares to the other...

Well it said using ONLY these items so that threw me off a little. But okay. Thanks much.

Homework Statement How would you determine the resistance value of an unmarked resistor with only a voltmeter, a battery, and servreal resistors of known value. Explain the method to determine the value of the unmarked resistor using only these items. I don't know whether or not a circuit...

A copper block rests 30.cm from the center of a steel turntable. The coefficient of static friction between the block and the surface is .53. The turntable starts from rest and rotates with a constant angular acceleration of .50 rad/s^2. After what time interval will the block start to slip on...

i sort of drew a diagram of the forces, but still didn't really get it.

i just took one look at the problem and my mind went blank. i totally do not know how to start it.

with a constant applied force of 85.0 N that acts at an angle of 55.0° with the horizontal. the block accelerates to the right at 6.00 m/s². determine the coefficient of kinetic frction between the block and the ceiling.

reaching level ground at the bottom with a speed of 7.0 m/s. the coefficient of kinetic friction between the sled's runners and the hard, icy snow is 0.050, and the girl and sleed together weight 645 N. how far does the sled travel on the ground level before coming to rest?
