The flow of air caused by ____ and the Coriolis effect creates distinct wind patterns on Earth's surface.

Answers

The correct answer to the question above is the difference in heating. Th flow of air is caused by the difference in heating and the Coriolis effect creates distinct wind patterns on the Earth's surface.

Answer:

Unequal heating of the earth surface.

Explanation:

Wind refers to the moving mass of air. It originates due to the unequal heating of the surface of the earth that takes place because of the heat energy provided from the Sun. This difference in the heating of the earth's surface give rise to the formation of the low pressure and the high pressure zone. The wind flows from the region of high pressure zone to a region of low pressure zone.

This wind flow is affected by the Coriolis force that comes into the picture because of the rotation of the earth, that allows the wind to move in a distinct pattern in both the hemispheres. It flows in clockwise manner in the northern and anticlockwise manner in the southern hemisphere.

What's is 18/10 in a %

Answers

Hey There Kash,

What's is 18/10 in a %?

Converting a fraction such as 10/18 into a percent is pretty easy.

All you have to do is divide the numerator by the denominator and then multiply that result with 100 like so:

(Numerator/Denominator)*100

When you enter 10/18 into the above formula, you get (10/18)*100 which calculates to: 

55.56%

Answer: 55.56
to find a percentage of a fraction just take the numerator (top) and divide it by the denominator (bottom) the multiply that by 100 to figure out the percent. so your answer is 180%

Based on this chart, what is the marginal cost, in dollars, to produce two jackets?a. 5
b.15
c.18
d. 33

I had fallen asleep in economics and I need help with the question being asked. The answer and explanation would be great! Thank you!

Answers

ANSWER: b.15

EXPLANATION: The marginal cost to produce two jackets is $15. The definition of Marginal Cost is the additional cost that is involved to produce one additional unit of product or service. In this table, the cost of producing the first jacket was $18 and the total cost of producing two jackets is $33. So, subtracting the total cost from the cost of producing the first jacket we get, $33 - $18 = $15, which is the marginal cost.
The marginal cost for two jackets is B. 15
