Answer:
Density is defined as mass per unit volume. its SI unit is: kg/m³
Explanation:
Answer:
The gravitational potential energy of the nickel at the top of the monument is 8.29 J.
Explanation:
We can find the gravitational potential energy using the following formula.

Identifying given information.
The nickel has a mass
, and it is a the top of Washington Monument.
The Washington Monument has a height of
, thus we need to find the equivalence in meters using unit conversion in order to find the gravitational potential energy.
Converting from feet to meters.
Using the conversion factor 1 m = 3.28 ft, we have

That give u s

Finding Gravitational Potential Energy.
We can replace the height and mass on the formula

And we get


The gravitational potential energy of the nickel at the top of the monument is 8.29 J.
