What is the angular speed of the rotating coil?

22.  A 0.256kg plastic ball is tied to 1 end of a 0.85m long string and is swung in a horizontal circle. If it takes 1.08s to complete 1 circle, what is the acceleration of the ball?   ac=19.89ms2   ac=28.77ms2   ac=24.22ms2   ac=30.32ms2   None of these is correct.

e. Calculate the total energy dissipated in the loop during the first 6 seconds.

Q.1) For the crane figure, compute the tensions in cables AC and BC A shown in 50 fa if a = 20°. Use sine and cosine law only. 12 kN B Draw whatever need.

A transformer is designed for use in a neon sign. The input voltage is 120 V and the output needs to be 3000V. The output current is 50mA.  1. If 100 turns are placed on the primary coil, how many turns will need to be on the secondary coil? 2. What is the current in the primary set of coils? 3. What is the power output of the transformer?

attempt if you have done Waves) In the figure below, all components are conducting hence force a conducting loop. The vertical sides of the loop are made of springs with k = 2 N/m and the conducting rod on the bottom has length = 30 cm and mass m = 20 g. A uniform magnetic field of strength 0.4 T is perpendicular to the plane of loop and into the page. X X X e x X X
