When a crest-trough meet the interference produced will be destructive in nature hence they both will cancel out and the amplitude produced will be equal to zero hence the loudness will reduce to zero.

A fighter plane is flying overhead at mach 1.50. What angle does the wave front of the shock wave produced make relative to the

olga2289 [7]

Answer:

θ = 41.80°

Explanation:

Given that

Mach number M= 1.5

We know that

M = u/c

Where c is the velocity of sound and u is the speed of plane

c= 340 m/s

u = 1.5 x 340 m/s

u = 510 m/s

We know that

$sin\theta =\dfrac{c}{u}$

Now by putting the values

$sin\theta =\dfrac{c}{u}$

$sin\theta =\dfrac{340}{510}$

θ = 41.80°

So the angle will be 41.80°.

What is the thinnest soap film (excluding the case of zero thickness) that appears black when illuminated with light with a wave

Llana [10]

Explanation:

It is given that,

The thinnest soap film appears black when illuminated with light with a wavelength of 535 nm, $\lambda=5.35\times 10^{-7}\ m$

Refractive index, $\mu=1.33$

We need to find the thickness of soap film. The soap film appear black means there is an destructive interference. The condition for destructive interference is given by :

$2t=m\dfrac{\lambda}{\mu}$

t = thickness of film

m = 0,1,2....

$\mu$ = refractive index

$t=m\dfrac{\lambda}{2\mu}$

$t=\dfrac{\lambda}{2\mu}$

For thinnest thickness, m = 1

$t=1\times \dfrac{5.35\times 10^{-7}\ m}{2\times 1.33}$

$t=2.01\times 10^{-7}\ m$

Hence, this is the required solution.

An airplane awaiting departure is cleared to takeoff, its accelerates down a runway at 3.20m/ s2 for 32.8s until it finally lift

stich3 [128]

The final velocity before takeoff is 104.96 m / s.

<u>Explanation:</u>

The last velocity of a given object over some time defines the final velocity. The final velocity of the object is given by the product of acceleration and time and adding this product to the initial velocity.

To calculate the final velocity,

V = u + at

where v represents the final velocity,

u represents the initial velocity,

a represents the acceleration

t represents the time taken.

$v = 0 + (3.20)\times( 32.8)$

v = 104.96 m / s.
