An airplane is flying with velocity of 70km\hr in north east direction .The wind is blowing 30km\hr from north to south. What is the resultant displacement of the aeroplane in 4 h

The resultant displacement of the airplane in 4 hours is 212.8 km.

Explanation:

The components of the airplane's velocity and wind's velocity are:

Airplane:

Wind:

Now, to know the new velocity of the airplane we to find the result vector:

Now, the magnitude of the new speed of the airplane is:

Finally, after 4 hours the resultant displacement of the airplane is:

Therefore, the resultant displacement of the airplane in 4 hours is 212.8 km.

I hope it helps you!                                        

d) physical means can be used to separate the components of air.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
