Are there any difference betwn supersonic planes and concorde planes

Answer:

Yes, there are differences between supersonic planes and concorde planes

Explanation:

The supersonic planes moves faster than the speed of sound. But these flights are banned because it is economically non-starter.  It has more loud sound equivalent to the explosion. The banned was elevated in 2003, due to new aviation law. The concords travel twice the speed of sound. This planes holds the record for the fastest planes but seen to be fleet long back i.e. in 2003. These were banned when a fatal crash had been reported. And now are only found in the museums.  

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
