Explanation:
Degausser is a device used by automatically manipulating the alignment of magnetic domains on the medium to avoid data stored on computer and laptop hard disks, floppy disks, and magnetic cassette. There was a mistake. Therefore, a degausser is used to remove all audio, video and data signals from magnetic store media completely.
The time of flight of
the dart is 36.761 s, it can be used to solve the initial velocity of the dart
bt the formula t= 2v/g, which v is equal to 180.31 m/s which is actually very
fast. We can now solve the maximum distanc H= v^2/2g which is equal to 1657.11
m.
The reason the large jet was seen, but wasn't heard till a few seconds afterwards, is solely because of the speed of light, rather than sound. We know that light is very, very fast. It's faster than sound! That means that answer choices A, B, and D have been eliminated. You now get:
C) The speed of light is faster than the speed of sound.
