Hello!
Let's solve this!
In this link we will find the image of the problem.
https://smart-answers.com/physics/question14138735
Regarding that image, we will first calculate the distance from my position to S1 and then to S2. Then the difference between these results.
We will use pitagoras.
S1 =
S1 = 24.17
S2 =
S2 = 22.56
The difference will be:
24.17-22.56 = 1.61 m
Constructive interference:
Δr=n*λ
λ=1.61 m (for n = 1)
Then we will calculate the frequency:
f = v / λ
f = (343m / s) /1.61m
f = 213.04 Hz
So the correct answer is option 213.04 Hz

The centripetal acceleration is given by
where v is the tangential speed and r the radius of the circular orbit.
For the car in this problem,
and r=40 m, so we can re-arrange the previous equation to find the velocity of the car:
where v is the tangential speed and r the radius of the circular orbit.
For the car in this problem,
Answer:
10.4 m/s
Explanation:
The problem can be solved by using the following SUVAT equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time
For the diver in the problem, we have:
is the initial velocity (positive because it is upward)
is the acceleration of gravity (negative because it is downward)
By substituting t = 1.7 s, we find the velocity when the diver reaches the water:
And the negative sign means that the direction is downward: so, the speed is 10.4 m/s.
