Answer: C. Shadow length decreased from sunrise to noon.

Explanation: Think about how the sun is positioned in the sky. If it was noon, the sun is above the stick which means little to no shadow at all. If the sun was rising, its hitting one side of the stick, making the shadow longer.

During each heartbeat, about 80 g of blood is pumped into the aorta in approximately 0.2 s. during this time, the blood is accel
aivan3 [116]
I assume that in this item, we are asked to solve for the force exerted during the heartbeat. Force is the product of the mass and acceleration. To solve for the acceleration in this item, we divide the velocity by time.
                                   a = 1 m/s /  0.2 s = 5 m/s²
Then, we multiply this by the mass (in kg)
                                  F = (80 g / 1000 g/kg) x (5 m/s²)
                                      = 0.4 kg m/s² = 0.4 J
Therefore, every hearbeat will take 0.4 J of force.
