Answer:

Their relative speed is 44 m/s

Explanation:

* <em>Lets explain what is the relative speed</em>

<u><em>Relative motion</em></u> is the change in position with time of one object

compared to another object.

If objects moving in the <em>same direction</em> towards, or away from, each

other, then relative speed is ⇒ <em>fastest speed – slowest speed</em>

If objects moving in <em>opposite directions</em> towards, or away from, each

other, then relative speed is ⇒ <em>the sum of the two speeds together</em>

* Lets solve the problem

Two cars are travelling side by side down a straight road in opposite

directions.

Both cars are travelling at a speed of 22 m/s

The two cars are travelling in opposite direction, then the relative

speed is the sum of their speed together

They are travelling at the same speed 22 m/s.

Then their relative speed = 22 + 22= 44 m/s

* <em>Their relative speed is 44 m/s</em>

What does K stand for in Hookes law?
wlad13 [49]
So Hooke's law says that that law is proportional to how much I stretch the spring. Alright. So f=kx<span>. x is the length of the spring now minus its length when it's relaxed and nobody's pulling on it. k is a constant called the spring constant.</span>

A sound wave travels in air toward the surface of a freshwater lake and enters into the water. The frequency of the sound does n
Shkiper50 [21]

Answer:

Explanation:

velocity of sound in air at 20⁰C is 343 m /s

velocity of sound in water at 20⁰C is 1481 m /s

The wavelength of the sound is 2.86 m in the air so its frequency

= 343 / 2.86 = 119.93 .

This frequency of  119.93 will remain unchanged in water .

wavelength in water = velocity in water / frequency

= 1481 / 119.93

= 12. 35 m .
