The is true because I said so
The aspect of his fitness program that could keep the young man from achieving his goal would potentially be the exercise with his friend. His friend could be a hindrance to his motivation to do more or to continue. If he's so attached with exercising with his friend and his friend decides to stop, then he would probably lose motivation.
Answer:
Hooke's law describes the elastic properties of materials only in the range in which the force and displacement are proportional. Hooke's law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. the maximum extent to which a solid may be stretched without permanent alteration of size or shape, is called elastic limit

Answer:
c. -14,000
Explanation:
Workdone by gas is the product of the pressure and the volume where there is a change of volume.
If v1 is the initial volume of the gas and v2 is the final volume of gas, the work done
= p(v2 - v1)
where p is the pressure
and p = 70,000 Pa
Given that volume decrease by 0.2m^3, v2 - v1 = -0.2
Workdone = 70000 ( -0.2)
Workdone = -14,000 J
Option c. -14,000
