Higher-frequency sound waves are perceived as having _____.A. higher pitch
B. lower pitch
C. higher volume
D. lower volume

Answers

Answer 1

Answer: higher frequency sound waves are perceived as having higher pitch

Answer 2

Answer:

Final answer:

Higher-frequency sound waves are perceived as having a higher pitch. This is because the pitch of a sound, which our brains perceive as either high or low, is directly related to the frequency of the sound wave. Finally, the volume or loudness of a sound is related to the amplitude of the wave, not its frequency.

Explanation:

Higher-frequency sound waves are perceived as having a A. higher pitch.

The pitch of a sound is directly related to its frequency. In other words, as the frequency of a sound wave increases, the pitch that we hear also increases. Thus, sounds with higher frequencies are heard as having a higher pitch. This is why when you tune a musical instrument, increasing the tension of a string will increase its frequency of vibration, producing a higher pitch.

On the other hand, volume, also known as loudness, is related to the amplitude of sound waves, not their frequency. So higher-frequency sound waves are not necessarily louder or softer, their volume depends on other factors such as the amplitude of the wave.

How does a pulley make it easier to load cargo onto a cargo ship?A.
The pulley increases the force needed to lift the load by moving it over a longer distance. It also changes the direction of the force. As the input force is applied downward, the output force is exerted upward.

Answers

Answer:

The pulley reduces the force needed to lift the load by moving it over a longer distance. It also changes the direction of the force. As the input force is applied downward, the output force is exerted upward.

Explanation:

When we use pulley system to pull the heavy weight then it is easier to pull the weight upwards because while we use use pulley to pull the objects then the force that is applied on the string is exerted at some angle with the vertical

Due to this we need to apply force at some angle with the vertical and it increase the output force on the object which is to be pulled

So here our effort is in downward direction to pull the object in upward direction

so correct answer will be

Light traveling through air at 3.00 · 10^8 m/s reaches an unknown medium and slows down to 2.00 · 10^8 m/s. What is the index of refraction of that medium? n =

Answers

v 1= 3.00 · 10^8 m/s
v 2 = 2.00 · 10^8 m/s
The index of refraction:
n = v 1 / v 2 = 3.00 · 10^8 m/s : 2.00 · 10^8 m/s = 1.5
Answer:
The index of refraction of that medium is 1.5

Answer

The index of refraction of medium is 1.5 .

Explanation:

Equation for index of refraction is given by .

$n = (c)/(v)$

Where n is index of refraction in medium , v is speed of light in the medium and c is the speed of light in air .

As given

Light traveling through air at $3.00* 10^8$ m/s reaches an unknown medium and slows down to $3.00* 10^8$ m/s.

$c = 3.00* 10^(8)$

$v = 2.00* 10^(8)$

Putting the values in the formula

$n = (3.00* 10^(8))/(2.00* 10^(8))$

Solving the above

n = 1.5

Therefore the index of refraction of medium is 1.5 .

Terminal velocity and Inicial velocity they are related???

Answers

Well the only relation they have is that they are both velocities.

The initial velocity of an object is the velocity it begins moving with. i. e if a ball is thrown its initial velocity is the velocity it has once it leaves the hand.

Terminal velocity is the maximum velocity an object can achieve when it is in free fall. i.e if a bowling ball is dropped from a plane, its velocity will increase until it reaches terminal velocity.
