The work done in stretching the spring from 50 cm to 80 cm is 67.5 J.
<h3>Hooke's Law</h3>
Hooke's law states that the force applied to an elastic material is directly proportional to its extension, provided its elastic limit is not exceeded.
To calculate the amount of work done by Hooke's law, first, we need to find the force constant of the spring.
Formula:
- F = ke................. Equation 1
Where:
- F = Force applied
- k = Spring constant
- e = extension
make k the subject of the equation
- k = F/e................ Equation 2
From the question,
Given:
- F = 450 N
- e = 30 cm = 0.3 m
Substitute these values into equation 2
Finally, To find the work done in stretching the spring from 50 cm to 80 cm, we use the formula below.
- W = ke²/2........... Equation 3
Where:
- W = Work done
- k = spring constant
- e = extension
Also, From the question,
Given:
- e = (80-50) = 30 cm = 0.3 m
- k = 1500 N/m
Substitute these values into equation 3
- W = 1500(0.3²)/2
- W = 67.5 J.
Hence, The work done in stretching the spring from 50 cm to 80 cm is 67.5 J.

Answer:
Convection is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Condensation is the process by which water vapor in the air is changed into liquid water. Condensation is crucial to the water cycle because it is responsible for the formation of clouds. These clouds may produce precipitation, which is the primary route for water to return to the Earth's surface within the water cycle.
