What is the voltage between two points if 1.2 J of energy are required to move 0.4 mC between the two points?

3000V

Explanation:

we have the following:

Energy (is this case the energy comes from the work of moving the charge):

charge:

And the formula to find the voltage between two points given the energy and the charge is:

substituting all the known values:

the voltage needes is 3000 volts

change tension

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
