3. If 2 J of wok is done in raising a 180 g apple, how far is it lifted?

1.13m

Explanation:

From the question, we obtained the following information:

W = 2J

m = 180g

We must convert this gram (i.e 180g) to kg

1000g = 1Kg

180g = 180/1000 = 0.18kg

g = 9.8m/s2

h =?

w = mgh

h = w / mg

h = 2 / ( 0.18x9.8)

h = 1.13m

it becomes positively charged by charging it

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.
