One star has a mass slightly more than the mass of the sun. which of these graphs would best model and predict the lifetime of the star on the main sequence?
a) a graph comparing stellar mass (x-axis) and main sequence lifetime (y-axis). the line graph shows a steep decrease in stellar mass from left to right.
b) a graph comparing stellar mass (axis) and main sequence lifetime (y-axis). the line graph shows a steep increase in stellar mass from left to right.
c) a graph comparing stellar mass (axis) and main sequence lifetime (y-axis). the curve shows a steep increase, then a decrease in stellar mass from left to right, peaking at the half-way mark.
d) a graph comparing stellar mass (axis) and main sequence lifetime (y-axis). the curve shows a steep decrease, then a increase in stellar mass from left to right, showing the lowest point at the half-way mark.

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.)
