question 4-7 4. Travelling Waves and Their Characteristics A rope wave travels in the positive x -direction. You are also told that the speed of the wave is 1000 cm/s, its frequency is 200 Hz, and that the wave is subject to the following initial conditions: at x 0 and t = 0: y =-1 cm, and, at x = 0 and t : ar = +20 cm/s (this is the velocity of the point on the rope at horizontal...

A still Alpha particle (charge amount 320*10 C. mass-6.65 10 kg) is placed between the two parallel plates below with electric potential difference of 2500 V. The distance between the two parallel plates is 5 om battery a Find the electric force acting on the alpha particle. (2 marks) b. Find the acceleration of the alpha particle. You may ignore its gravity force acting on it this time because it is too tiny in comparison to its electric force (2...

3. Fill the blanks and the Proof - J.J. Thomson's experiment to fine the charge-to-mass ratio of the tt) (25 points) electron (i.e. e/m; The first is the experiment of Joseph John Thomson, who first demonstrated that atoms are actually composed of aggregates of charged particles. Prior to his work, it was believed that atoms were the fundamental building blocks of matter. The first evidence contrary to this notion came when people began studying the properties of atoms in large...
