For a report I have to answer a few questions but I don't understand it!
- Look up the speed of sound of 0 °C.
- The speed of a fighter jet is often expressed in Mach. 'Mach 1' is exactly the same as the speed of sound, for which 340 m/s is taken. An F-16 can reach a top speed of 2100 km/h. How big is the speed of speed in Mach?
- Calculate how long it will take before you get an answer from a 1.1 km deep echo well.
Do you understand this? Thanks in advance. Greets Noah.
