The Speed Of Sound Quick Check
1.) Which statement correctly compares the speed of sound in solids and gases?
-The speed of sound is generally faster in solids than in gases, because solids are denser than gases.-
2.) The speed of sound through diamond is about 12,000 m/s. The speed of sound through wood is about 3,300 m/s. Which statement explains why the speed of sound is different through these materials?
-They have different rigidities.-
3.) Based on the table, which statement describes the relationship between temperature and the speed of sound in water?
-Sound travels faster in warmer water, both in fresh water and sea water.-
4.) A student conducts an experiment in which sound waves pass through air and then through water. Which statement describes the wave speed as it passes from air to water?
-The speed of sound increases.-
5.) Why does sound travel the slowest in air?
-The distance between molecules of air is greater than for molecules of water.-

The speed of sound quick check, 100% :)
Can't believe somebody really got on here and named themselves cum_bucket
I am inclined to agree but wish I saw other choices.
still right today
crazy usernames out here dawg
100% correct!
ikr
yup still right
Guys we should all start putting our physical science quick checks on here (but dont waste space with random stuff, just give it a thumbs up if its right) this will make it easier for all us cheaters to get our answers, ill start
Waves in Different Media Quick Check
1.) Which measure does not change when a wave moves from one medium to another?
ANSWER - frequency
2.) Water waves approaching the shore will slow down. Which statement describes another change that occurs?
ANSWER - The wavelength decreases
3.) As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?
ANSWER - The speed will triple, and the frequency will stay the same
4.) Sonar systems used in water send out sound waves that reflect off the environment and then are detected. As water gets denser, the speed of sound in water increases. What would happen to the wavelength of a sonar wave as it moves into water with a 5% higher speed of sound?
ANSWER - The wavelength would increase by 5%
5.) An earthquake sends seismic waves outward from the epicenter. The waves travel through different media in different directions. What will be true for all people who feel the earth shaking?
ANSWER - The earth will rise and fall with the same frequency
Wave application Quick Check
doing the questions is too much work so heres just the answers
300 m
20 to 120 hertz
10 meters
sound A, because it has a higher frequency
0.375 to 3 meters
Wavelength in Different Media
The sound of a plucked guitar string travels through the air and strikes the eardrum of a person in the same room. How does the sound wave change when it transfers from the air to the person’s eardrum?
ANSWER - Both the speed and the wavelength of the sound change.
The table shows the speed of sound in various media. Which list orders the media from shortest wavelength to longest wavelength for sound waves that pass through them?
ANSWER - air, water, glass, steel
Two different types of rope with different properties are fused together to make one long rope. When a wave transfers from the first type of rope to the second type of rope, the wavelength becomes one-fourth of what it was before the transfer. What is true about the speed of the wave?
ANSWER - The speed of the wave becomes one-fourth its original speed after the transfer.
If a sound wave transitions from one medium to another, which transition would result in a shortening of the wavelength of the sound wave?
ANSWER - steel to water
If an ultrasound wave moves from one tissue to another tissue in the body, which of the following transitions will result in the largest change in the wavelength of the ultrasound wave?
ANSWER - blood to fat
Digital and Analog Systems Quick Check
1.) What kind of code is generally used for sending digital information?(1 point)
-binary code 1s and 0s-
2.) Which statement describes a drawback of digital medical records over paper records?(1 point)
-Digital medical records might be impossible to access in a power outage-
3.) Which statement is a fair comparison of the advantages and disadvantages of paper versus digital financial records?(1 point)
-Digital records are easier to store-
4.) Which phrase describes an analog signal and not a digital signal?(1 point)
-smooth sinusoidal waves-
weakinsomniac is right
Okay Bot, will do. You can leave now.
Pros and Cons of Digital Systems Quick Check
just the asnwers, its easier
Online banking is more convenient, but personal information can be stolen.
Cash can be used without a device, but it takes up space.
Other researchers around the world can access it.
Noise, or signal interference, is unlikely to impact the results.
There may be multiple holes punched or not punched all the way.
yeah ik right.
quizlet.???/792685518/physical-science-b-semester-exam-costal-connections-acdeamy-flash-cards/
this is for the physical science b semester exam
(add com where it says ??? right after quizlet,you cant post urls so i had to do it this way)
Luna is far to late to have said anything
lmfao
LMAO love how nut_cumsumer says that about Cum_bucket
Weak Insomniac is correct
