An airplane flies at airspeed (relative to the air) of 280 km/h . the pilot wishes to fly due north (relative to the ground) but there is a 52 km/h wind blowing southwest (direction sehgal (ts35972) – homework 3 – markert – (54390) 4 225◦ ). in what direction should the pilot head the plane (measured clockwise from north)?

the pilot should head the plane towarrds south- west

Solution:

The airspeed of the airplane, v = 280 km/h

The velocity of the wind, v' = 52 km/h South-west

Angle,

Now, measured angle in the clockwise direction from North:

Now,

south- west

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
