The potential energy of a body can be found by using the formula

PE = mgh

where

m is the mass

h is the height

g is the acceleration due to gravity which is 10 m/s²

From the question we have

PE = 45 × 10 × 2

We have the final answer as

The mass of a solid substance is 21.1164 g. If the volume of
GuDViN [60]

Answer:

The density of the  substance is 1.0611 \frac{g}{cm^{3} }

Explanation:

The density of a substance is a characteristic property that matter, whether solids, liquids or gases, has to be compressed in a given space, that is, it allows us to measure the amount of mass in a certain volume of a substance.

Density is expressed as follows:

density=\frac{mass}{volume}

In this case:

  • density: ?
  • mass: 21.1164 grams
  • volume: 19.9 cm³

Replacing:

density=\frac{21.1164 grams}{19.9 cm^{3} }

density= 1.0611 \frac{g}{cm^{3} }

<u><em>The density of the  substance is 1.0611 </em></u>\frac{g}{cm^{3} }<u><em></em></u>
