its said that the average value of a sin wave is zero volts so
1) the voltage we measure by voltmetre in ac is 110 or whatever its not zero?
2)how to measure the measure value of a sine wave by the help of a multimeter??
3)how to measure pulsating dc by a voltmeter yeah but on AC setting or DC setting?
4)if the average valuse of pulsating dc is measured will it be zero?
thanks plz do categerize ur answer by question numbers

PLEASE ONLY OBJECTIVE, SCIENTIFIC ANSWERS. I am not interested in any philisophical or religious takes on this issue. It would be great if I could start a dialogue amoung Chemists / Biochemists on this issue. (I am a Chemistry major at Ohio State and I just finished the third of three organic chem classes.)

A shiny new sports car sits in the parking lot of a car dealership. Above is a cargo plane, flying horizontally at 50m/s. At the exact same moment the plane is 125m directly above the car, a heavy crate acedientally falls from its cargo doors. Relative to the car, where will the crate hit?

The answer is 250m away from the car.
How do you do it?
