quiz 12/10

Question 1

pressure

Answer 1

force over area

Question 2

force

Answer 2

N

Question 3

area

Answer 3

m^2 or cm squared

Question 4

bernovillis principle

Answer 4

as the speed of a moving fluid increases, the pressure w/in it decreases

Question 5

pascals principle

Answer 5

when pressure is applied to a confined fluid, that pressure is transmitted equally to all parts of the fluid

Question 6

Cartesian diver

Answer 6

squeeze bottle at top thing floats to bottom and etc

Question 7

hydrolic system

Answer 7

big syringe doesn’t take much pressure to pop little syringe (f over a)

Question 8

hydrolic system continued example problem

Answer 8

if 10 N of force or applied to a 5cm squared piston connected to 15cm squared what is the output force? 10 over 5 equals F over 15

Question 9

buoyancy

Answer 9

upward force in water/liquid

Question 10

displacement

Answer 10

the amount of liquid moved by a submerged or partially submerged object

Question 11

Archimedes principle

Answer 11

• buoyant force acting on a submerged or partially submerged object is equal to the weight of the fluid displaced by it
• the volume of fluid displaced is equal to the volume of the submerged portion of the object

Question 12

density

Answer 12

breaks your heart (m over v) floats or sinks
