Answer:

Explanation:
Potential energy is minus the integral of Fdx. Doing the integration yields:



so


Now for x=3.0m


Answer:it’s different materials have different abilities to transfer energy.
Explanation:
Just took it.
Answer:
Plutonium, has formula Pu with molecular mass 94
Explanation:

Answer:
0.1587
Explanation:
Given data
μ = 0.5 mg
standard deviation σ =0.1 mg
n=100
we know that


putting the values we get

Z=-1
Area under the curve for z =-1 is 0.1587 (from z score table)
P(X<0.49) = 0.1587
P(X<0.37) = 0.0013
