To raise a 0.48-kg box from a shelf, 6 J of work is done. How far was the box lifted from the shelf? Round your answer to the nearest tenth.

The height through which the box was raised is 1.3 m.

Explanation:

Given;

mass of the box, m = 0.48 kg

work done in raising the box, W = 6 J

The work done in raising the box is calculated by work-energy theory; the work done in raising the box is equal to gravitational potential energy of the box due to the height it was raised.

W = P.E = mgh

where;

h is the height through which the box was raised

g is acceleration due to gravity = 9.8 m/s²

Therefore,  the height through which the box was raised is 1.3 m.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
