Prove that, s=u+v/2<br>please I need help

Hoochie [10]

Answer:

Actually the formulae is S=(u+v/2)t

.TO explain,from average velocity=distance /time

and average velocity is u+v/2

hence using the formular

Average velocity=distance/time

distance will be=average velocity ×time

so S=(u+v/2)t

Two identical loudspeakers are some distance apart. A person stands 5.20 m from one speaker and 4.10 m from the other. What is t

Igoryamba

Answer:

125.09 Hz

Explanation:

Given : A person stands 5.20 from one speaker and 4.10 m away from the other speaker.

Distance between the speakers is 5.20 - 4.10 =1.10 m

We know that

For destructive interferences

n . λ / 2

where n =1,3,5,7....

Therefore difference between the speakers is

5.10 - 4.20 = 1 X 0.5 λ

λ = 2.2

Given velocity of sound is V = 344 m/s

Therefore frequency, f = $\frac{v}{\lambda }$

= $\frac{344}{2.2 }$

= 156.36 Hz

Now, the third lowest frequency is given by

λ = (5.20-4.10) X 5 X 0.5

= 2.75 m

Therefore frequency, f = $\frac{v}{\lambda}$

= $\frac{344}{2.75}$

= 125.09 Hz

Therefore third lowest frequency is 125.09 Hz
