3. What is the role of neutrons in the nucleus?

Answers

Answer 1

Neutrons are electrically neutral, but contribute to the mass of a nucleus to nearly the same extent as the protons. Neutrons can explain the phenomenon of isotopes (same atomic number with different atomic mass). The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.

Answer 2

Answer:

The main role of neutrons is to reduce electrostatic repulsion inside the nucleus.

Explanation:

:) Good luck my friend

Different isotopes of an element can exist. For example, Carbon can have a mass number of 12 or a mass number of 14. Carbon always has an atomic number of 6.

Describe the difference between these two isotopes of Carbon.

In your answer, compare the number of protons, neutrons and electrons.

Answers

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.

Answers

Answer:

[tex]a=\frac{v^2}{r}[/tex]

[tex]v=\sqrt{a*r}[/tex]

[tex]r=\frac{v^2}{a}[/tex]

Explanation:

This is the formula for centripetal acceleration in terms of the tangential velocity (v) and the radius of the circular motion (r). The expression for the acceleration is already given, so simply type it as shown:

[tex]a=\frac{v^2}{r}[/tex]

For the velocity (v) multiply by "r" both sides and then use the square root to solve for v:

[tex]a*r=v^2\\v=\sqrt{a*r}[/tex]

For the radius multiply both sides by r and then divide both sides by the acceleration (a) in order to isolate r completely:

[tex]a*r=v^2\\r=\frac{v^2}{a}[/tex]

You are the coach of a basketball team that is currently looking for new players. One of the criteria for selection as a player is that the person must be above a particular height. Ideally, you want your next player to be as tall as possible. However, you do not want to rule out any potential players by making the cut-off height too strict. You decide that accepting players within the top 2.5% height bracket will be reasonable for your team. Assume that the height of all people follows a normal distribution with a mean of 69 in and a standard deviation of 2.9 in. Calculate the cut-off height (C) that ensures only people within the top 2.5% height bracket are allowed into the team. you may find this standard normal table useful.
