Anna applies a force of 84n Nto lift her baby nephew 2.0 m. How much work
does Anna do? Answer

168 J

Explanation:

Work can be calculated using the following formula.

w=f*d

where w is work, f is force, and d is distance.

Anna applied a force of 84 Newtons, and lifted the baby 2.0 meters.

f=84 N

d=2 m

Substitute these variables into the formula.

w=84 N* 2 m

Multiply

w=168 N-m

A N-m is the same as a Joule, or J.

w= 168 Joules

Anna does 168 Joules of work.

the answer is tropical areas. the tropical areas obtain more

radiant energy from the sun than they lose to space through terrestrial

radiation, and vice versa for polar areas. earth has an energy remaining in the

tropics and an energy scarcity for the polar areas.
