Carbon-14 atom have 6 protons plus 8 neutrons.
Explanation
Carbon-12 and Carbon-14 are examples of isotopes of carbon that have huge applications in the field of science.
Isotopes are those elements who have equal number of protons and electrons whereas their neutrons differ.
Therefore isotopes have same atomic number, as atomic number depends on number of protons or number of electrons whereas number of neutrons do not have a role in atomic number.
But mass numbers of isotopes are different as mass numbers depend on the number of protons and number of electrons.

Entropy, in thermodynamics, is a measure of the degree of randomness or disorderliness of a system. It has units of energy per temperature. So, we calculate it by dividing the total heat in the system by the temperature. We do as follows:
Entropy = 437 J / 321 K = 1.36 J/K
The only thing you need to know in order to solve this task is that <span>plank length (which is force x), should equal the increase in potential energy, so what we have now : (mass)* g * (height).
It has to look like that: </span>
<span>F * 3.0 = 150 x 9.81 x 1.20
Then solve for F, the result should be in newtones = 588N
Do hope it makes sense.</span>
