When using a lever, what needs to happen in order to increase the size of the output force and to raise the mechanical advantage of the lever?

Explanation:

They are,

1.Moving the load closer to the fulcrum will increase the mechanical advantage.

2.Moving the effort farther from the fulcrum will increase the mechanical advantage. This may require a longer lever.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

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.
