Use ohm’s law to calculate the voltage of a car battery when the current is 2.0 amps and the resistance is 6.0. show work

If the speed of a particle triples ,by what factor does its kinetic energy increase?

What should the power status of a circuit be when measuring resistance with an ohmmeter?

The 10-kg double wheel with radius of gyration of 125mm about o is connected to the spring of stiffness k = 600 n/m by a cord which is wrapped securely around the inner hub. if the wheel is released from rest on the incline with the spring stretched 225 mm, calculate the maximum velocity v of its center o during the ensuing motion. the wheel rolls without slipping
