Am going nuts If a vehicle has a mass of 750 kg
a) What is its weight on earth? Take gravity to be 10 Nkg-1
b) If the gravity on the moon is 1/6th that of the earth, calculate the weight of the car on the moon
c) Given that F = ma, calculate the force needed to move the vehicle with an acceleration of 5ms-2.

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?

1) what is the power in horsepower of a 100 watt light bulb? what is the power in kilowatts of a 200 horsepower engine? 2) if a cars engine is providing 3000 n of force to keep the car moving at 5 m/s, what is the engine’s effective power? 3) how many gallons of water will be pumped from a well 30 feet deep by a 1/2 hp engine in 1 minute? (1 gallon weighs 8.34 pounds)
