As you found out in the previous part, bernoulli's equation tells us that a fluid element that flows through a flow tube with decreasing cross section moves toward a region of lower pressure. physically, the pressure drop experienced by the fluid element between points 1 and 2 acts on the fluid element as a net force that causes the fluid to

a. decrease in speed
b. increase in speed
c. remain in equilibrium

B. increase in speed

Explanation:

Bernoulli's principle states that, in a constant flow, the sum of its kinetic energy, its potential energy and its internal energy, remains constant. A pressure drop implies an decrease in the sum of its potential energy and its internal energy. Thus, this implies an increase in its kinetic energy, that is, an increase in the fluid's speed.

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

c.the charges if the proton and electron and gravity
