FULL ANSWER

Neutrons and protons make up a nucleus and they are in the middle of an atom. Electrons surround the nucleus. Opposite charges attract each other. Because of this, protons do not attract other protons and electrons do not attract other electrons. Instead, protons attract electrons and electrons attract protons. When someone looks at the elements on the periodic table, they can see how many protons are present by looking at the atomic number. Since atoms have to have an equal amount of each, if an element contains 36 protons, it also has 36 electrons.

Answer:

From your frame of reference, the speed of your friend is zero.

Explanation:

The speed from a frame of reference is the magnitude of the change of the position per unit of time in that frame of reference.

When it is said that, to a stationary observer you have a speed of 9m/s, it means that the observer "measures" tha your position, in a moment, changes 9 m per second.

Since both you and your friend are sit still on the same spinning merry-go-round, neither of you will change positions with respect to the other, meaning that you will perceive that your friend will not move, from your frame of reference. That is, if you are isolated from the rest of the universe, and the merry-go-round continues spining uniformly, you cannot detect any movement of your friend, which means that from your frame of reference, the speed of your friend is zero.
