When the temperature of a metal cylinder is raised from 0.0°C to 110°C, its length increases by 0.22%. Find the percent change i
monitta
<span>Volume of cylinder = pi*r*2*L

As, from the above formula,volume is directly proportional to length, 
So, if we increase in length also increases in volume by 0.22%

we know 

</span><span>density=<span><span>mass/</span><span>volume

As, density is inversely proportional to volume it means increasing in volume decreases the density by 50.22%

Wave travelling along right with speed of 0. 5 m/s time 4 second point p
Soloha48 [4]

The wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.

<h3>What is the speed of wave?</h3>

Speed of wave is the rate by which the wave travels. It can be described as the distance cover by the crest or thrust of it per unit of time. It can be calculated with the following formula,

v=f\times\lambda

Here, (f) is the frequency and (λ) is the wavelength.

The frequency is inverse of time. Thus, the value of frequency in time t is,

f=\dfrac{1}{t}\\f=\dfrac{1}{4}\\f=0.25

The speed of the wave is 0.5 m/s. Put the values in the formula,

v=f\times\lambda\\0.5=0.25\times\lambda\\\lambda=\dfrac{0.5}{0.25}\\\lambda=2

Thus, the wavelength of the wave which is travelling along right with speed of 0. 5 m/s time 4 second point is 2.
