A wire in a circuit carries a current of 0.9 A. Calculate the quantity of charge that flows through the wire in 50 s.

Give the correct unit with your answer.

Use the equation: charge = current x time

What are the theoretical properties of a gas at a temperature of 0 kelvin?

What sort of waves exhibit the doppler effect?

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
