To Explain: Mass defect and to what it is related.

Answer to Problem 47A
Mass defect is defined as the change between the sum of masses of all the particles of a nucleus and also the mass of the nucleus. The mass defect is related to the binding energy.
Explanation of Solution
Introduction:
The nuclear binding energy is used to divide the atom into different parts that includes protons, neutrons and nucleons. It is always positive as all the nuclei require a fix amount of energy to divide them into protons and neutrons.
Mass defect is the change between the sum of masses of all the particles of a nucleus and also the mass of the nucleus
The original mass is always less than sum of each mass of the protons and neutrons as energy is removed when there is formation of nucleus. This mass is called as the mass defect which can be removed and can be calculated by the sum of total mass of the actual particles.
This type of defect is called as the mass defect which is not present in the nucleus and is used to represent the energy which is released when the nucleus is formed.
Conclusion:
A mass defect denotes to the change in the mass between an atom and sum of masses of the neutrons, protons, and electrons of an atom.

Starting from rest, each cube moves down through a net vertical distance of h = 1.50 m and leaves the bottom end of the track at an angle of 40.0° above the horizontal. At the highest point of its subsequent trajectory, the cube strikes a vertical wall and rebounds with half the speed it had upon impact.

If Thor wants to reach escape velocity (velocity needed to leave Earth’s atmosphere), he will need the linear velocity of the center of mass of the hammer to be 11,200 m/s. Thor's escape velocity is 33532.9 rad/s, the angular velocity is 8055.5 rad/s^2.
