- hands start getting sweaty
- nail biting or perhaps shaking legs
- the feeling of being overwhelmed
- (for some people) the stomach starts to hurt
OK, its deff not the last one b/c all that trash just goes into the air, overwater farm land would kill crops (no help there), Ive never heard of heating water to kill excess bacteria. There is ,however, a new technique called Bioremediation which is the use of living organism to clean up a medium i.e. air,soil, water. It would seem the 2nd answer is correct.
Answer:
250J
Explanation:
Given parameters:
Spring constant = 500N/m
Extension = 1m
Unknown:
Elastic potential energy = ?
Solution:
The elastic potential energy of a body is the energy stored within an elastic string.
EPE = 
k e²
k is the spring constant
e is the extension
Now;
EPE = x 500 x 1² = 250J
I think the answer is Joule.
As an amount of energy (being transferred), the SI unit of heat is the joule (J).
