You move a 4 N object 10 meters. Find work.
Then find power if it is done in 5 seconds.

W= 40 J

P = 8 W

Explanation: Solution for work:

W = F d

= 4N ( 10 m)

= 40 J

Solution for Power:

Power is the ratio between work per unit time.

P = W /t

= 40 J / 5 s

= 8 W

i don't know, you need to give me some answers.

explanation:

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.
