According to Pascal, pressure applied to a fluid __________.
|A)||decreases as it moves through the fluid|
|B)||increases as it moves through the fluid|
|C)||is transmitted unchanged throughout the fluid|
|D)||fluctuates as it is transmitted throughout the fluid|
Bernoulli's principle states that as the velocity of a fluid __________, the pressure exerted by the fluid __________ .
A(n) __________ uses a fluid to increase an applied force.
|A)||wheel and axle|
A force of 150 N is applied to a 25 cm 2 piston in a hydraulic machine. What is the area of a larger piston if the force available in it is 450 N?
The area of the small piston in a hydraulic system is 1 m2. The area of the larger piston is 4 m2. If a force of 10 N is applied to the small piston, what is the force available in the large piston?
|D)||Not enough information is given.|
How does Bernoulli's principle explain how airplanes fly?
|A)||Air pressure is greater on the top of the wings, creating lift.|
|B)||The backward force exerted by an engine creates an equal and opposite push, resulting in lift.|
|C)||Air pressure is greater below the wings, creating lift.|
|D)||The air pressure on top of the wing is equal and opposite to the air pressure on the bottom, creating a balanced upward force.|
