Two factors affect the speed of a sound wave as it travels through a medium

Answers

Answer 1

Answer:

Answer: The density and the temperature

Explanation:

Sound needs a medium to travel. The medium particles vibrate and transfer energy. Sound travels by compression and rarefaction of the medium particles. Thus, the speed of the sound varies with the density of the medium. If the medium is denser, the particles would be closer and energy would transmitted faster because there would be more rapid collisions which means that speed of the sound will be greater in a denser medium.Thus, speed of sound is fastest in solids than in liquids and is least in gases.

Speed of sound also depends on temperature. Greater the temperature, the particles would vibrate faster which would lead to again more inter particle collisions. Thus, the speed of sound would increase with increase in temperature.

Answer 2

Answer: The density of the medium and temperature affect the speed of sound waves.

a car is moving with a constant speed of 20 meters per second.What total distance does the car travel in 2 minutes

Answers

There are 120 seconds in two minutes, so to find the answer, you multiply 20 x 120 to get 2400 meters.

Final answer:

The car travels a total distance of 2400 meters in 2 minutes at a constant speed of 20 meters per second.

Explanation:

Distance is the measurement of space between two points, typically in terms of length or spatial separation. It is a fundamental concept used in various fields, including physics, geography, and mathematics.

To find the total distance travelled by the car in 2 minutes, you need to calculate the distance covered in 1 second and then multiply it by the number of seconds in 2 minutes.

Since the car is moving at a constant speed of 20 meters per second, the distance covered in 1 second is 20 meters.

To find the total distance, multiply 20 meters by 60 seconds (1 minute) and then again by 2 (number of minutes).

The total distance travelled by the car in 2 minutes is 2400 meters.

Which statement is true about the loudness of sound?A. It is directly proportional to the distance of the listener from the source.

B. It is inversely proportional to the square of the distance of the listener from the source.

C. It is directly proportional to the square of the distance between the listener from the source.

D. It is inversely proportional to the distance between the listener from the source.

Answers

Answer : The correct option is, (B)

Explanation :

There is a direct relation between the loudness of sound and the intensity of sound.

$L=10\log (I)/(I_o)$ ..........(1)

where,

L = loudness of sound

I = intensity of sound

$I_o$ = intensity of reference

From this we conclude that the loudness is directly proportional to the intensity of the sound.

There is an indirect relation between the intensity of sound and the distance of the listener from the source.

$(I_1)/(I_2)=((d_2)/(d_1))^2$ ...................(2)

From this we conclude that the intensity of sound is inversely proportional to the square of the distance of the listener from the source.

From equation (1) and (2) we conclude that the loudness of sound is inversely proportional to the square of the distance of the listener from the source.

Hence, the correct option is, (B)

Just like the gravitational force, the electrostatic force, the perceived
brightness of a light, and the strength of a radio station . . .

The loudness of a sound is inversely proportional to the square of
the distance between the observer and the source.

A tennis ball is dropped from 1.16 m above theground. It rebounds to a height of 0.866 m.
With what velocity does it hit the ground?
The acceleration of gravity is 9.8 m/s

Answers

Final answer:

Using the principles of free fall motion, it can be determined that a tennis ball dropped from a height of 1.16 meters would hit the ground with a velocity of 4.8 m/s.

Explanation:

The objective here is to calculate the initial velocity of the tennis ball just before it hits the ground. This is a physics question related to free fall motion. We will use the equation of motion, v^2 = u^2 + 2as, where 'v' is the final velocity, 'u' is the initial velocity, 'a' is the acceleration, and 's' is the distance. In our case, the initial velocity (u) is 0 because the ball is dropped, not thrown downwards.

The acceleration (a) is the acceleration due to gravity, which is -9.8 m/s² (it's negative because it acts downwards). The distance (s) will be the drop height, which is -1.16 m (it's negative because we're considering downwards as negative direction). Therefore, the equation becomes (v)^2 = 0 + 2*(-9.8 m/s²)*(-1.16 m). Solving this we get v = √(2*9.8*1.16) m/s = 4.8 m/s. So, the tennis ball hits the ground with a velocity of 4.8 m/s.

Why was the concern over global cooling replaced with a concern over global warming?

Answers

During 1970s, same observations were seen as what we have observed today pertaining to our climate. Journals were discussing that there would be warming because of greenhouse gases emissions. Also, it was observed between the years 1970 to 1990 that there was a steady surface temperature increase. Due to this, people are now fixated with global warming rather than on global cooling.
