____________________ A clapper stays in synch with the echo of the clapping. During ten seconds of clapping there were 40 claps. The echo flight distance out to the building and back was 87 meters. Determine the speed of sound based on this data.
On the diagram below, draw the path of a light ray from the penny to the eye.
____________________ The experimental data obtained during laboratory nine measured the speed of sound to be 363 m/s. The speed of sound predicted by theory is 350 m/s at 28° Celsius, 80% humidity, and pressure of 1002 mPA. What is the percent difference between the experimentally measured value and the value predicted by theory? 1

____________________ Lightning is the result of a high voltage electric current being passed through the air. Will lightning generate a continuousordiscrete spectrum?
____________________ A Haier microwave oven consumes 1250 Watts at 120 volts. Use the mathematical relationship power = current × voltage to calculate current i in amperes used by the microwave.
____________________ A Haier microwave oven consumes 1250 Watts at 120 volts. Use Ohm's law and the result above, voltage = current × resistance to calculate the resistance R of the microwave in Ohms (Ω)?
