EXAM 1

Question 1

Sound

Answer 1

Alberse, in the strictest sense sound is a compressional wave that produces a sensation in the human ear

Question 2

what are the 4 attributes of sound?

Answer 2

pitch, loudness, quality, and duration

Question 3

compressional wave

Answer 3

in order for something to make a sound it needs to vibrate to make sound

Question 4

what are the two properties that something must have to make sound?

Answer 4

mass and elasticity

Question 5

medium

Answer 5

through which sound is transmitted

Question 6

mass

Answer 6

amount of matter present which is capable of vibratory motion

Question 7

weight

Answer 7

gravitational force exerted on a force

Question 8

mass

Answer 8

is a quantifiable amount

Question 9

elasticity

Answer 9

property of all matter be it solid, liquid, or gas which allows it to undergo distortion in either shape or volume when force is applied

Question 10

elastic limit

Answer 10

the point at which the mass is unable to return to its original form after distortion

Question 11

equilibrium (E)

Answer 11

the state of rest

Question 12

amplitude

Answer 12

going to be dependent on the amount of force
greater the force the greater the displacement

Question 13

Newton First Law of Motion

Answer 13

all body’s remain at rest or in uniform motion unless another force acts in remission

Question 14

inertia

Answer 14

nothing more than the tendency of body to stay in motion tendency of body at rest to stay at rest

Question 15

Newton Third Law

Answer 15

for every force there must be equal associated in recreational force

Question 16

________ and ___________ are no longer able to work together in relationship

Answer 16

mass and elasticity

Question 17

cycle

Answer 17

equilibrium to point of maximum displacement in 1 direction through equilibrium to maximum displacement in opposite direction to equilibrium

Question 18

what happens when a force is applied to molecules?

Answer 18

each molecules is equal distance from each other, exerting equal pressure on each other never touching each other

Question 19

density

Answer 19

amount of mass per unit volume

Question 20

change of density

Answer 20

it changes because of density

Question 21

compression

Answer 21

the reduction in volume (causing an increase in pressure) of the fuel mixture in an internal combustion engine before ignition.

Question 22

rarefraction

Answer 22

air rebounds have fewer air molecules there is a decrease in air pressure fewer than at equilibrium

Question 23

when we introduce a vibrating source to a median that sound is transmitted through median in

Answer 23

alternating compression and rarefaction
