Calculate the slope of the line on the graph using the formula: m = m = v subscript 2 - v subscript 1 over x subscript 2 minus x subscript 1. The slope of the line is m/s.

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head

hope this !

305.7

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7

in four significant figures
