Physics

The scientist that shot alpha particles into gold was Earnest Rutherford. He discovered about electrons. Then, later, he tried to prove that atoms had neutrons. This was done with his gold foil experiment. When the atoms were shot and hit the nucleus, they bounced back... that is how he found out that the atoms had a nucleus, also where our nuclear structure of an atom comes from...

Hope this helps;)

The Geiger–Marsden experiment(s) (also called the Rutherford gold foil experiment) were a landmark series of experiments by which scientists discovered that every atom contains a nucleus where its positive charge and most of its mass are concentrated

Rubbing both pieces cause each piece to have a negative charge.

When two parts have the same they repel each other, so holding one piece up tot he end of the other piece would push it away.

Because one piece is held in the middle by a string, it would rotate the piece in a circle.

If they held the piece to the other end of the one held by a string it would start to rotate in the opposite direction.

Let's see

Use snells law

\\ \rm\Rrightarrow \dfrac{n_1}{n_2}=\dfrac{sini}{sinr}

\\ \rm\Rrightarrow \mu=\dfrac{sin30}{sin19.9}

\\ \rm\Rrightarrow \mu=0.5/0.34

\\ \rm\Rrightarrow \mu=1.47

It may be glass
