The 3 major parts of the cell are :
Plasma Membrane - the outer covering of the cell that encloses the cytoplasm.
Cytoplasm - the jelly like matrix within the cell that contains the various organelles.
Nucleus - round and usually centrally placed structure that controls the various activities of the cell.
I hope this will be helpful i made a bold assumption of speed of sound since it is not provided
The correct answer is C.
We will use Boyle's law that states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
P1 V1 = P2 V2
Where
P1 is initial pressure = 5 psi
V1 is initial volume = 20 cubic inch
P2 is final pressure = 10 psi
V2 is final volume = unknown
V2 = P1,V1 / P2
V2 = 20 × 5 / 10
V2 = 100/10
V2 = 10 cubic inches
Answer:
<u>Amplitude - remains the same</u>
<u>Frequency - increases</u>
<u>Period - decreases</u>
<u>Velocity - remains the same.</u>
<u />
Explanation:
The amplitude of the wave remains the same since you are not changing the distance your hand moves and the amplitude of the wave depends on how much distance your hand covers while moving.
The frequency of your wave increases since now you are moving your hand more number of times in the same period i.e. your hand is moving faster in one second. So, the frequency of your wave increases.
The period is the time taken by the wave to travel a certain distance. Since your hand is now moving faster, the wave will travel faster and will take less time to cover the same distance hence, we can say that its period will decrease.
The velocity of a wave depends on the medium in which it is travelling. Your wave was previously travelling in air and the new wave is also travelling in the same medium so the velocity of the wave remains unchanged.

Type the correct answer in the box. Spell all words correctly. Stephen is a student who wants to test his knowledge of medical terminology. <u>Which option could he use?</u>
For medical terminology, ___________ can include a single word part on one side, with the meaning on the other side. Stephen can test himself or can enlist the help of someone else to hold them up to test him.
Answer:
<u>Flashcard</u>
Explanation:
It is interesting to note that a flashcard is an effective memory and teaching aid. It usually<em> has a question on one side, and the other side contains the answer.</em>
Hence, Stephen can build his knowledge of medical terminology by making use of a flashcard himself or can enlist the help of someone else to hold them up to test him.
