Question

an astronaut takes a tuning fork with her to the moon she strikes it inside the cabin the cabin is normally filled with air so the humans inside the spacecraft are comfortable she also strikes it outside the spacecraft when she gets down on the surface of the moon which of the following is true about the tuning fork? A: it does not vibrate inside the spacecraft B: id does not vibrate on moon surface C: it vibrations are not transmitted inside the spacecraft D:it's vibrations are not transmitted to the moon's atmosphere

Answer 1

Answer:

D. Its vibrations are not transmitted on the moon's surface

Explanation:

Sound needs a medium to travel, as it travels in the form of compressions and rarefactions which are created by regions of high air pressure and low air pressure. And we know that moon does not have an atmosphere, well technically it has a very thin layer on which isn't really an atmosphere but is instead an exosphere. So when the tuning fork is struck on the moon, the sound created by it will not travel, since there is no medium and as discussed before, sound needs a medium to create regions of high pressure and low pressure which is not possible on the moon.
