the law of conservation of momentum states that, if left alone what happens to the total momentum of two interacting objects that make up a system

Explanation:

false....it is joules

..........

The answer is false

The SI unit for energy is joules and not Newton. Energy can be described as the capability of an individual to perform work. Every day all living things carry out one form of work or the other. These might include walking, running, cooking, singing, driving etc. All these activities require energy, some require a whole lot of energy.

This is why the importance of energy for our day to day activities cannot be over emphasized.

Hence the SI UNIT for energy is joules.

Answer:

chris gets 960 and molly gets 1440

Explanation:

add the ratio up and divide

2+3=5

2400/5=480

480x2=960

480x3=1440

960+1440= 2400

Answer:

C. amount of charge on the source charge.

Explanation:

Electric field lines can be defined as a graphical representation of the vector field or electric field.

Basically, it was first introduced by Michael Faraday and it is typically a curve drawn to the tangent of a point is in the direction of the net field acting on each point.

The number, or density, of field lines on a source charge indicate the amount of charge on the source charge. Therefore, the density of field lines on a source charge is directly proportional to quantity of charge on the source.

The energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

In physics, energy is the capacity to carry out work. It might be potential, kinetic, thermal, electrical, chemical, radioactive, etc., among other types. Heat and work are other examples of energy being transferred from one body to another. Once it has been transmitted, energy is always allotted according to its nature. As a result, heat transmission could result in thermal energy while effort could provide mechanical energy.

Given the information in the question:

The potential difference, V = 12 Volts,

The charge, q = 7.5 C,

Calculate the energy, E by the formula given below,

E = [tex]VQ[/tex]

Substitute the values of charge and potential difference,

E = [tex]12*7.5[/tex]

E = [tex]90 Joules[/tex]

Therefore, the energy is transferred when the potential difference is 12 volts and the charge is 7.5 C is 90 Joules.

Answer:

Carbon 14 has 2 more neutrons than Carbon 12

same number of protons and electrons if they are both neutral atoms (that is the +  or - aspect)

Explanation:

Answer:

The difference is the number of neutrons they have.

Explanation:

The atomic number is the number of protons. The number of protons is what differentiates elements. The isotope number is the total weight of the atom, that is the protons plus the neutrons. Therefore the number of neutrons is equal to the atomic mass minus the atomic number. Electrons are generally equal to the number of protons, to balance the charge of the atom.

In short: the difference between the two isotopes is that one has more neutrons.
