Answer:
We know that potential energy is the energy that is stored within an object while kinetic energy is the energy that is in motion. The connection between the two is that potential energy transforms into kinetic energy.
Explanation:
Your question answer is here
a. Solution ,
Given volume (V)=30cm^3
Mass = 180 g
Density =?
We know that,
Density = given mass/volume
Or. 180/30
=6g/cm^3
b. We know ,
If any pice of stone have equal density so each piece have 6g/cm^3
c. We know ,
Given weight = 80g
Density = 6g/cm^3
Volume =?
We know that,
Volume = given weight ( mass)/ density
= 80/6
= 13.33 cm^3
