The Cosmoclock 21 Ferris wheel in Yokohama City, Japan, has a diameter of 100 m. Its name comes from its 60 arms, each of which
can function as a second hand (so that it makes one revolution every 60.0 s).
Find the speed of the passengers when the Ferris wheel is rotating at this rate.

Answer:
3 Minutes 2 seconds to 22 minutes 16 seconds
Explanation:
Lets assume the Mars to be at the closest distance to Earth. This distance (D) = 54.6 Million km
The signal travels at the speed of light, so speed of the signal (V) = 300000 km/s
So, the time (T) taken by the radio wave to reach Earth from Mars will be,
Thus, T = 182 Sec = 3 Minutes 2 seconds.
The radio wave will take minimum 03 Minutes 02 seconds to reach Earth. Here is should be noted that the distance between the two planets keep on changing as they revolve around the Sun. There will come a point when Mars is farthest from Earth and the distance (D) will be 401 Million km. Then, the time will change to ,
T = 1336.67 sec = 22.27 Minutes.
So the maximum time will be 22 minutes 16 seconds.
Answer:Changing Length
Explanation:
We know the Resonant frequency depends upon length and varies as inversely to the length of air column
thus by changing the length of Pipe we can chnge the frequency
