An airplane is pushed 22 degrees eastward off its northward course by a jet stream traveling at a speed of 136.73 km/hr. the new speed is 365 km/hr. find the plane's original velocity.

As the speed of airplane is change due to jet stream

So the net speed is given as

now we can rearrange it as

now by the formula of vector difference we have

now plug in all values

so above is the speed of the plane

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

they should be similar or the same
