You already determined that the speed of sound is 348m/s. You then find that an unlabeled tuning fork produces a soundwave with a
wavelength of 0.25 meters.
What can you conclude about that tuning fork?
It produces a sound with a pitch of 44 Hz
It produces a sound with a volume of 44 dB
It produces a sound with a pitch of 1392 Hz
It produces a sound with a pitch of 1740 Hz
It produces a sound with a volume of 1740 dB
It produces a sound with a volume of 1392 dB
It produces a sound with a volume of 87 dB

It equals just about 6,300 km per hour each day an week

Perhaps seek some professional ? it isn't very asking some children who are just trying to find out answers to homework.also, it seems professional would actually be good to you. obviously it isn't going to magically fix your depression, but it'll do something. drugs, smoking weed, it won't do much, especially if your husband is against it. if you do it he'll dislike it. but talk to him, try and get him to listen to you, and figure everything out together, okay? there's a website- maybe it can offer some ?
