Answer:

28.8 degrees bearing above from the east.

Step-by-step explanation:

Given :

Direction =30 degrees

Speed =724 km/hr

Suppose x1, y1 be the velocity bearing in the east at the 30 degree

so x1 velocity = 724 cos 30 degree

y1 velocity = 724 sin 30  degree

As mention in the question the wind speed adding another 32 to the x1 speed.

Hence the resultant speed  is

velx1= 659\\vely1 = 362

The \ speed\  is\ determined \ by \ following\ formula\ \\ \sqrt{vel y1^2+ velx1^2} \\= \sqrt{659^2+362^2}\\=751.9 km/hr\\therefore\  \ the\  direction is\  arctan \\= vely1/ velx1 \\= arctan( 362/659) \ =28.8\  degrees\ above\ from\  the\  east

Orchids are a family of thousands of types of flowers that all share the same shape. Many gardening clubs are devoted to collect
irakobra [83]

Answer:

The correct options are;

1) Which type needs the highest temperature to grow

2) Do all of the types make food the same way

3) How long does it take for a specific type to make seeds

Step-by-step explanation:

The number of types of species in the orchid family = Several thousand

The tasks the gardening clubs are devoted to = Collecting, Studying, and growing of the orchids

The manner of the growth of the orchids = Difficulty observed in growing outside the orchid's natural habitat

Scientific questions are objective questions that are measurable, well defined about parameters that can be controlled which can be answered by means of an experiment and meant to provide a deeper understanding of the nature of the world around us

Therefore, the scientific questions that can be asked about a collection of different orchid types are;

1) Which type needs the highest temperature to grow

The above is a question that has a defined parameter (temperature) which is measurable and the answer can be provided by experimenting

2) Do all of the types make food the same way

An experiment with different orchid types will provide an answer to the above question

3) How long does it take for a specific type to make seeds

The length of time for it takes the seed to grow is measurable within an experiment.
