Answer:
<em>113.4 J</em>
Explanation:
<u>Elastic Potential Energy</u>
Is the energy stored in an elastic material like a spring of constant k, in which case the energy is proportional to the square of the change of length Δx and the constant k.

The spring has a natural length of 0.7 m and a spring constant of k=70 N/m. When the spring is stretched to a length of 2.5 m, the change of length is
Δx = 2.5 m - 0.7 m = 1.8 m
The energy stored in the spring is:

PE = 113.4 J
Answer:
This is because spirit has a lower boiling point when compared to water
Explanation:
spirit has a lower boiling point when compared to water which means it has the capacity to pull more heat from your hand and also it can do this very fast. This is why our hand feels colder.
Force= mass x acceleration
79=mass(3)
m=79/3
m=26.3 kg
A decagram is 1000 times bigger than a centigram
Force is the agent which causes a change in the velocity of an object and thereby to acellerate it inertia on he other hand is a property which realtes to an intrinsic of a body to resist any change in its state rest or of emotion uniform or non uniform
