No, because 25% of their energy needs is not worth it.
Units of force are the newton pound.
Answer:
The answer to your question is c 11 because the number of neutrons plus protons equals the atomic mass.
Explanation:
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
As we know that, f=ma where
f= net force
m=mass of body
a=acceleration
Substitute m and a in the formula and you will get the answer
