The answer for Plato users is C. It is the energy that is required to overcome mass defect.

From Plato "Nuclear binding energy is the energy that is required to overcome the energy that is used to keep the nucleus together, the mass defect."

Option (B) is the correct answer.

Explanation:

As nucleus of an atom contains protons and neutrons and due to the same charge present n protons there will occur repulsion.

Hence, a binding energy will act on the nucleus of an atom which will bind the protons and neutrons together. When this binding energy is greater than the force of repulsion between the sub-atomic particles of a nucleus then the atom is stable.

Therefore, to change the nucleus of an atom high amount of energy is required. As a result, nuclear reactions tend to release large amount of energy due to changes in the nucleus of an atom.

Thus, we can conclude that the statement it is the energy that is required to bind protons and neutrons together in a nucleus, best describes nuclear binding energy.

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
