independent variable:
increasing the pressure of gas
dependent variable:
decrease in volume
Answer:
a. 0.98 J
b. -0.98 J
c. 306.25 J/m²
Explanation:
(a)
(b)
The increase in gravitational potential energy = decrease in elastic potential energy
Elastic potential energy = -0.980 J
(c) The spring constant can be calculated as follows:
