Given :

A person stands 6.00 m from a speaker, and 8.00 m from an identical speaker.

To Find :

The wavelength of the first (n = 1) interference minimum (destructive).

Solution :

Since speaker are identical so they are in same phase.

For first destructive construction difference between the distance should be equal to half the wavelength .

So, 8-6 = \dfrac{\lambda}{2}\\\\\lambda = 4 \ m

Frequency is given by :

\nu = \dfrac{343}{4}\ Hz\\\\\nu = 85.75 \ Hz

Hence, this is the required solution.

Imagine that you are approaching a black hole in a spacecraft. What would you see? What would happen to you?
HACTEHA [7]
As you approach the event horizon, your body would be pulled towards the black hole. It's a process called sphagettification.

Here's a quote from an article explaining this.
And gravity from the black hole is starting to pull on your feet more than your head. "The gravity wants to sort of stretch you in one direction and squeeze you in another," says Joe Polchinski.<span>
</span>
As for what you see, that is hard to explain without showing a video, at least for me, but you would see this black hole (ha) and whatever is outside starts to flatten and condense (from your POV) then you would fall into the black hole and then it's complete blackness.

But all of this is just educated guessing, and honestly, you'd be dead before anything would happen.

URGENT PHYSICS QUESTION WILL GIVE BRAINLIEST
Morgarella [4.7K]

Answer:

7.2V

Explanation:

Find the equivalent resistance:

Req = 10 ohms + 15 ohms = 25 ohms

Use ohm's law to find the current:

V = IR

12V = I(25 ohms)

I = .48 amps

Multiple the current with the value of R2 to get the voltage drop:

.48amps x 15 ohms = 7.2V

A red laser beam goes from crown glass with refraction index n=1.3 to air (n=1) with an incident angle of 0.23 radians. What is
Klio2033 [76]

Answer:

   θ = 10.28º

Explanation:

To find the angle of refraction use the equation of refraction

        n₁ sin θ₁ = n₂ sin θ₂

where index 1 is for incident light and index 2 is for refracted light.

         sin θ₂ = n₁ / n₂ sin θ

let's calculate

         sin = 1 / 1.3 sin 0.23

         sin = 0.175

        θ= 0.17528 rad

let's reduce to degrees

       θ = 0.17528 rad (180ª / pi rad)

       θ = 10.28º
