Question1

It has been asserted that a permanent magnet is really just made up of an insulator with fixed positive electrical charges permanently embedded in the north pole of magnet and fixed negative electrical charges permanently embedded in the south pole of magnet.

(a) Do you think this assertion?

(b) Name three observations you made that would offer support for or evidence against this assertion. Cite Activity numbers and describe how each observation supports your conclusion.

Question2

A transverse sinusoidal wave on a string has a period of 10.4 ms and travels in negative x direction with a speed of 45.9 m/s. At t = 0, a particle on the string at x = 0 has a displacement of 1.65 cm with a transverse speed of 0.955 m/s.

What is amplitude of the wave? Give Answer in units of m

What is initial phase angle? Give Answer in units of degree

What is the greatest transverse speed of the string? Give Answer in units of m/s

What is wave number? Give Answer in units of m−1
