The wavelength of a sound wave is related to its frequency by the relationship:
where
f is the frequency
v is the speed of the wave
is the wavelength
The wave in our problem has wavelength of
and speed of
(this is the speed of sound in air), therefore its frequency is
And the period of the wave is equal to the reciprocal of its frequency:
As a horse finishes its trot around the corral, it slows from 4m/s to a stop in 3
seconds. Calculate the acceleration of the horse.
Can anybody help ?
Answer:true
Explanation:
It takes the moon approximately a month to complete an orbit round the earth
Answer:
0.24 seconds
Explanation:
The signal will reach the computer at light speed = 
Distance between the satellite and the computer = 
Since, the bodies have no acceleration relative to each other we use the following formula
Time = Distance / Time
One way delay would be at least 0.12 seconds.
But when you click on a link to open a website this signal has to be first sent to the satellite then the satellite would have to send the required signal back to the computer.
Hence, the minimum time delay would be 0.12+0.12 = 0.24 seconds
