What is the difference between a wave and a medium?

1 answer:

7 0

Answer:

Mediums in which the speed of sound is different generally have differing acoustic impedances, so that, when a sound wave strikes an interface between

Explanation:The propagation of a wave through a medium will depend on the properties of the medium. For example, waves of different frequencies may travel

If a car has a mass of 200 kilograms and produces a force of 500 N, how fast will the car accelerate?

Hitman42 [59]

Answer:

2.5m/s²

Explanation:

Given parameters:

Mass of car = 200kg

Force on car = 500N

Unknown:

Acceleration of the car = ?

Solution:

According to Newton's second law of motion:

Force = mass x acceleration

Insert the given parameters and find the acceleration;

500 = 200 x acceleration

acceleration = 2.5m/s²

An organ pipe is made to play a low note at 27.5 Hz, the same as the lowest note on a piano. Assuming a sound speed of 343 m/s,

timama [110]

Answer:

The length of open-open pipe needed is 6.23 m

The length of open-close pipe needed is 3.11 m

Explanation:

Fundamental frequency for standing wave mode of an open- open pipe is given by

$f=\frac{v}{2L}$

where v is the velocity and L is the length

The length of open-open pipe needed is

$L=\frac{v}{2f} \\L=\frac{343}{2\times 27.5} \\L=6.23 m$

Fundamental frequency for standing wave mode of an open- close pipe is given by

$f=\frac{v}{2L}$

The length of open-close pipe needed is

$L=\frac{v}{2f} \\L=\frac{343}{2\times 27.5} \\L=6.23 m$
