A jet plane passes over you at a height of 5870 m and a speed of Mach 1.47. (a) Find the Mach cone angle. (b) How long after the jet passes directly overhead does the shock wave reach you

(a) Angle is 42.865°

(b) t=12.54s

Explanation:

The jet plane is at 5870m from Earth surface

The jet traveling at speed of 1.47 Mach

Speed of Sound v=343 m/s

Part (a)

As we know :

Substitute the given values

Angle is 42.865°

Part (b)

As the distance given as:

By using some trigonometry

Where h is the height of jet plane

Thus

Substitute the given values

So

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

i think the answer would be b
