1. You've recently read about a chemical laser that generates a 20-cm-diameter, 25 MW laser beam. One day, after physics class, you start to wonder if you could use the radiation pressure from this laser beam to launch small payloads into orbit. To see if this might be feasible, you do a quick calculation of the acceleration of a 20-cm-diameter, 100 kg, perfectly absorbing block. What speed would such a block have if pushed horizontally 100 m along a frictionless track by such a laser?
3. In the figure below, the radius of the capacitor plates is R = 18.0 cm, the peak emf of the voltage source is 220 V and it oscillates at w = 130 rad/s.

Q4) Problem 51: Page No. 735 A radio station broadcasts at a frequency of 760 kHz. At a receiver some distance from the antenna, the maximum magnetic field of the electromagnetic wave detected is 2.15 x 10-11 T. (a) What is the maximum electric field? (b) What is the wavelength of the electromagnetic wave? (Ans: 6.45x103 V/m, 394.74 m) = C 3)
35.) How does a radio work?a. Radios use one signal to send to a receiver station which then uses the same signal to relay the communication b. Carrier waves cause the electrons in an antenna to vibrate, which causes a changing electric field that is amplified and sent to the speaker apparatus, producing sound. c. The electrical signal from a radio station is used to create radio waves that are transmitted to and from the microwave towers.
