One of the tallest buildings in the world is the taipei 101 in taiwan, at a height of 1671 feet. assume that this height was measured on a cool spring day when the temperature was 15.5°c. you could use the building as a sort of giant thermometer on a hot summer day by carefully measuring its height. suppose you do this and discover that the taipei 101 is 0.471 foot taller than its official height. what is the temperature, assuming that the building is in thermal equilibrium with the air and that its entire frame is made of steel?

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?

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
