Explanation:
u cant have a food chain with out the smallest part. in other words if a deer had no grass to eat it wouldn't be on the food chain because it didn't have grass, than the lion would then starve and slowly die out after the deer ext (you get it).
The value of the spring constant of the spring is 14.7 N/m.
The given parameters;
- <em>mass attached to the spring, m = 30 g</em>
- <em>length of the spring, L₀ = 10 cm</em>
- <em>angular speed of the mass = 90 rpm</em>
- <em>final length of the spring, L₁ = 12 cm</em>
The extension of the spring is calculated as follows;
The value of the spring constant of the spring is calculated by applying Hooke's law;
