In Thompson's cathode ray tube experiements, the electrically charged plates are created by a constant applied voltage, which maintains a constant positive charge on one plate and a constant negative charge on the other. Normal household voltage alternates 60 time per second (also called 60 cycles/sec or 60 Hz) between 110 volts and -110 volts. In the apparatus depicted attached graphics, what would we expect to see on the CRT, as configured if the charged plates are plugged into a wall socket, which would switch the charge on the plates from positive to negative 60 times per second

1. consider the case in which air fills air shocks on a truck trailer. the pressure in the shocks is 2 mpa. the temperature is 300 k. the diameter of the shock piston is 10 cm and the initial length of the cylindrical cavity containing the compressed air is 40 cm. a. the truck is gradually loaded over a period of a day in a static setting. the temperature is held constant for the atmosphere and thus for the gas shock. calculate the compressibility of the air in the shock for this condition when the truck is initially being loaded. b. if the shocks were loaded in a dynamic setting by driving over bumps, what would be the compressibility? state your assumption. c. what is the initial load on the shock if the shock is in an atmospheric 100 kpa? d. if the shock is compressed using the process described in part a, and the air shock compressed air cavity length decreases to 20 cm, what is the additional load applied to the shock?
