Answer 12

is the sum of atmospheric pressure and system pressure starting from a theoretical vaccum

Question 13

Pascals Law

Answer 13

Pressure applied to enclosed/confined fluid is transmitted equally in all directions without loss.

Question 14

Bernoulli

Answer 14

When pressure increases, velocity decrease.

When velocity increases, pressure decreases

Answer 15

Increase velocity/decrease pressure

Question 16

Divergent venturi tube

Answer 16

Decrease velocity and increase pressure

Question 17

Boyles Law

Answer 17

Increase pressure = decrease volume

Decrease pressure = increase volume

Question 18

Charles Law

Answer 18

Increase temperature = increase volume

decrease temp = decrease volume

Question 19

Answer 19

A mass at will remain at rest or in motion until acted upon by an outside force

Question 20

Newtons 2nd law - law of force and acceleration

Answer 20

when a body is acted upon by a constant force, its aceleration is inversely proportional to its mass

Question 21

Newtons third law - law of interation

Answer 21

for every action, there is an equal and opposite reaction
