Answer: Option (a) is the correct answer.

Explanation:

Using the Pythagoras theorem, we will calculate the the distance of S_{1}P and S_{2}P as follows.

        S_{1}P = \sqrt{(10)^{2} + (22)^{2}}

                   = 24.17

        S_{2}P = \sqrt{(5)^{2} + (22)^{2}}

                   = 22.56

Therefore, the path difference will be as follows.

           \Delta r = S_{1}P - S_{2}P

                      = 24.17 - 22.56

                      = 1.61 m

Formula for constructive interference is as follows.

                   \Delta r = n \lambda

                      \lamda = 1.61 m      (for n = 1)  

Therefore, frequency will be calculated as follows.

                  \nu = \frac{v}{\lambda}

                            = \frac{343}{1.61}

                            = 213.043 Hz

Thus, we can conclude that frequency produced by the speakers to create perfectly constructive interference is 213.04 Hz.

the car turned a corner going 10m/s if it took two seconds to turn what is its acceleration is this acceleration​
exis [7]

The acceleration of this car is equal to 5 m/s^2.

<u>Given the following data:</u>

  • Initial velocity = 0 m/s (assuming it's starting from rest).
  • Final velocity = 10 m/s.
  • Time = 2 seconds.

To determine the acceleration of this car:

<h3>How to calculate acceleration.</h3>

In Science, the acceleration of an object is calculated by subtracting the initial velocity from its final velocity and dividing by the time.

Mathematically,  acceleration is given by this formula:

a = \frac{V\;-\;U}{t}

<u>Where:</u>  

  • V is the final velocity.
  • U is the initial velocity.
  • is the time measured in seconds.

Substituting the given parameters into the formula, we have;

a = \frac{10\;-\;0}{2}

Acceleration, a = 5 m/s^2
