A sound wave produced by a chime 515 m away is heard 1.50 s later. What is the speed of the sound in the air?
aliina [53]

Answer:

the speed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance ÷ time

So, here speed be 515 m

And, the time is 1.50 seconds

So, the speed of the sound is

= 515 m ÷ 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s

A pail of water is rotated in a vertical circle of radius r = 1.6 m . The acceleration of gravity is 9.8 m/s 2 . r v What is the
Snowcat [4.5K]

Answer:3.95 m/s

Explanation:

Given

radius of circle r=1.6 m

Water will not spill if the centripetal acceleration is greater than acceleration due to gravity

i.e. a_c\geq g

a_c=\frac{v^2}{r}

\frac{v^2}{r}\geq g

v_{min}=\sqrt{gr}

v_{min}=\sqrt{9.8\times 1.6}

v_{min}=\sqrt{15.68}

v_{min}=3.95 m/s

Elastic Potential Energy: \displaystyle U_s = \frac{1}{2} k \triangle x^2

  • U is energy (in J)
  • k is spring constant (in N/m)
  • Δx is displacement from equilibrium (in m)
<h3>Explanation:</h3>

<u>Step 1: Define</u>

k  = 7.50 N/m

Δx = 0.40 m

<u>Step 2: Find Potential Energy</u>

  1. Substitute in variables [Elastic Potential Energy]:                                        \displaystyle U_s = \frac{1}{2} (7.50 \ N/m) (0.40 \ m)^2
  2. Evaluate exponents:                                                                                      \displaystyle U_s = \frac{1}{2} (7.50 \ N/m) (0.16 \ m^2)

In Young's double slit experiment, 402 nm light gives a fourth-order bright fringe at a certain location on a flat screen. What
Alex777 [14]

Answer:

λ₂ = 357.3 nm

Explanation:

The expression for double-slit interference is

          d sin θ = m λ                 constructive interference

          d sin θ = (m + ½) λ        destructive interference.

The initial data corresponds to a constructive interference, they indicate that we are in the fourth order (m = 4), let's look for the separation of the slits

         d sin θ = m λ₁

       

now ask for destructive interference for m = 4

        d sin θ = (m + ½) λ₂

we match these two expressions

         m λ₁ = (m + ½) λ₂

         λ₂ = ( m / m + ½) λλ₁  

let's calculate

         λ₂ =\frac{4}{(4.000 +0.5) \ 401}

        λ₂ = 357.3 nm
