B Yea that should be the right answer
Answer:
Explanation:
Let initial extension in the spring= x₀
Force on the spring = F₀
Let spring constant = k
Fo = k x₀
Fn = 3k x₀
Fn /Fo = 3
PEs0 ( ORIGINAL) =1/2 k x₀²
PEsn ( NEW) =1/2 k (3x₀)²
PEsn / PEs0 = 9
For number 11, you should say that there is more pollution and fossil fuels being burned.
Protons have a positive charge which is indicated by a + sign.
Hence, the answer is C.
