#3 The speed of sound is 346 m/s. If a sound wave travels at a frequency of 55 Hz, what would its wavelength be?

#4
If the same wave in question #3 travels through water with the same wavelength, at what frequency will it be traveling? (speed of sound in water = 350 m/s)

The first one is 6.3m or 6.25m

The second is 60 m/s

Explanation:

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
