If you set up an experiment with two different independent variables, then the results would be

To do work, this truck uses energy stored in chemical fuel and an electrical battery. how much total energy does this truck put out?

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Select all of the following that are equal to an impulse of 20 unitsa) force= 5, time= 5.5b) force= 25, time= 0.8c) force= 0.1, time= 200d) force= 10, time= 2(its b, c, and d)(also in order to find answer they have to add to get the unit)ex= 25x.8=20 or .1x200=20
