Physics Aviary: Practice Problems: Internal Resistance of Battery Problem

Determine the internal resistance of a battery based on the electrochemical potential and the voltage that is measured at the terminals of the battery when it is being used.

Determine the internal resistance of a battery based on the electrochemical potential and the current that comes out of the battery when it is hooked to a series of resistors connected in parallel.

In this problem you must determine the intensity of a sound wave when it reaches a given location away from its source.

Students must find out different things for a series of object's moving as a system with Friction. In this problem students will be given both a static friction coefficient and a kinetic friction coefficient.

Students must determine when a soccer ball reaches a given height based on the velocity with which it is kicked. Students are reminded that the ball will reach this height twice, once on the way up and once on the way down. Students must...

In this problem you must determine the height of a firework explosion above the ground.

In this problem you will have a tank of fluid get punctured and you will need to find the landing location of the fluid. The tank in which the fluid is housed is pressurized above the value of the atmospheric pressure.
