Calculate the average binding energy per nucleon of 24 12Mg. Answer in units of MeV/nucleon.

The average binding energy per nucleon of   is 8.00 MeV/nucleon

Explanation:

Here we have the molar mass of is 23.985042 amu

The mass of a proton = 1.007276 amu

The mass of a neutron = 1.008665 amu

From the notation, 1 Mg = has 12 protons and 12 neutrons

Therefore, we find the binding energy as follows;

= 12 × (1.007276) amu + 12 × (1.008665) amu - 23.985042 amu

= 24.191292 amu - 23.985042 amu = 0.20625 amu

1 amu = 931 MeV

Therefore, 0.20625 amu = 0.20625 amu × 931 MeV = 192.01875 MeV

The average binding energy per nucleon in   which has 24 nucleons, is thus;

= 192.01875 MeV ÷ 24 = 8.00078 MeV/nucleon ≈ 8.00 MeV/nucleon.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
