What is a shock wave and when is it produced

1 answer:

5 0

Shock waves can occur when an aircraft travels at the speed of sound or when a moving source of sound moves at the same speed as sound itself. Compressional wave fronts of the sound waves are "bunched" at the front cause some sort of stretch that when enough speed is accumulated, in this case, the aircraft will break the sound barrier and travel faster than the speed of sound. This is known as a Sonic Boom, and the aircraft involved is known as a supersonic aircraft. I hope you understand this now.

A student wishes to work out how much power she uses to lift her body when climbing a

Bess [88]

Answer

i'm not 100% sure but 1764

Explanation:

Work done = gravitational potential energy

Gravitational potential energy = mass(kg) × height(m) × gravitational field strength(N/kg)

We can assume that the student is on earth so the gravitational field strength is 9.8N/kg

So work done = 60 × 3×9.8

=1764

(if you need help calculating power but if you do just divide your answer by 12 and you will get 147)

Solar system help please!

Kobotan [32]

When one body(sun) exerts a force on a second body(planet), the second body simultaneously exerts a force equal in magnitude and opposite in direction of the first body. Which makes the planet orbit in path C.
