To practice problem-solving strategy 3.2 relative velocity. an airplane pilot wishes to fly directly westward. according to the weather bureau, a wind of 75.0 km/hour is blowing southward. the speed of the plane relative to the air (called the "air speed") as measured by instruments aboard the plane is 310 km/hour . in which direction should the pilot head?

The pilot should head 13.6° north of west.

Why?

We can solve the problem by using trigonometric relations. Since there is a right triangle formed between the direction that the pilot wants to fly to and the wind's speed, we can use the following formula:

Now, substituting the given information and calculating, we have:

Hence, we have that the pilot should head to 13.6° north of west.

Have a nice day!

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
