A ball is thrown vertically upward at 24.0 ms can reach a height of 28.8m ( neglecting air resistance).The speed, in m/s, when it is halfway to its highest point is (using g= 10 ms ^2)

True or false: the revolution of the earth creates day and night as it rotates around the sun

What is the average speed of a car that travels 40 mph for 1 hour and 60 mph in another hour?

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
