A = p + n (2) where n is the number of neutrons. When using atomic mass units (a.m.u.), the mass of each nucleon (proton or neutron) is 1 a.m.u, so the mass number also corresponds to the mass number.

Answer:
The North Atlantic Treaty or Washington Treaty
Explanation:
The North Atlantic Treaty or Washington Treaty is the treaty that constituted the North Atlantic Treaty Organization (NATO). It was signed in Washington on April 4, 1949.
There it is established that the purpose of NATO is to guarantee the freedom and security of its member countries through political and military means.
Answer:
Change volume / volume = .5 / 30 = .01666
coefficient of volume expansion = 3 * 24E-6 = 72E-6
Change in temp = .0167 / 24E-6 = 232 deg C
Final temp = 232 + 30 = 262 deg C
Change in volume / volume = 3 * coeff linear expansion * change in deg C
