Answer:
529.2 N
Explanation:
As we have studied the first law of motion, which states that every action has some reaction, equal in magnitude but having an opposite direction.
The force that is acting on the student will be due to gravitational force, that is equal to his weight.
F=mg: 54kg x 9.8m/s^2 =529.2 N
So the weight of student is exerting downwards towards the stool and land. The stool will also exert a force on the student that will be equal in magnitude but opposite in direction, then it will be 529.2 N.
This is because the student is sitting in a constant state and all the weight is exerted on the stool.
Note: This answer is very generic supposing that all the weight of the student is on stool. But, if we suppose that student's legs are on floor so it means the force of gravity acting on the stool has become less because student's mass on stool is less. So the answer would be a force somehow less than 529.2 N. However, since the question asked normal force, it would be weight of student in general terms.
Hope it helps!

<u>Answer:</u> The binding energy for lithium-6 nuclei is 3.09 E+11
<u>Explanation:</u>
Binding energy is defined as the energy which holds the nucleus together. It is basically the product of mass defect and the square of the speed of light.
This energy is calculated by using Einstein's equation, which is:
where,
E = Binding energy of the atom
= Mass defect = 0.0343g/mol = 
(Conversion factor: 
)
c = speed of light = 
Putting values in above equation, we get:
(Conversion factor: 
)
Hence, the binding energy for lithium-6 nuclei is 3.09 E+11
