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

c, 1a hope this

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!
