i need help answering 2 queshtions 

The left ventricle of a resting adult's heart pumps blood at a flow rate of
83.0 cm³ /s, increasing its pressure by 110 mm Hg, its speed from zero to 30.0
cm/s, and its height by 5.00 cm. (All numbers are averaged over the entire
heartbeat.) Calculate the total power output of the left ventricle. Note that most of
the power is used to increase blood pressure.
Select the correct answer
O 1.08 W
O 3.10 W
O 1.77 W
O 2.04 W
O 1.26 W

The arterioles (small arteries) leading to an organ, constrict in order to decrease
flow to the organ. To shut down an organ, blood flow is reduced naturally to 1.00%
of its original value. By what factor did the radii of the arterioles constrict? Penguins
do this when they stand on ice to reduce the blood flow to their feet.
Select the correct answer
O 0.100
O 0.0100
O 0.620
O 0.316
O 0.510
