Which statement describes nuclear binding energy?
(a)it is the difference between the masses of the protons and neutrons and the mass of the nucleus.
(b)it is the energy that is required to bind protons and neutrons together in a nucleus.
(c)it is the energy that is required to overcome mass defect.
(d)it is the energy that is required to overcome the electromagnetic force.
(e)it is the result of converting mass to energy.

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.

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
