Astudent would like to determine how heating a liquid changes its volume. the student hypothesizes that the liquid will increase in volume. the following list shows the steps taken by the student in order to test the hypothesis.
select the liquid to test.
place the liquid in a sealed container.
use a bunsen burner to heat the liquid by 10°c.
measure the volume of the liquid.
record the results.
what is wrong with how the student conducted the investigation?

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)
