Answer:
So high-frequency light has photons with high energies and appears blue in color. Thus amplitude and frequency are the two factors that affect the energy transferred by a wave: the height of the wave, and the number of waves passed by each second.
Explanation:
The correct answer is
B.
nitrogen, oxygen, argon, carbon dioxide
In fact, the abundance of the gases in the earth's atmosphere is as follows:
1) Nitrogen: 78.0 %
2) Oxygen: 21.0 %
3) Argon: 0.9 %
4) Carbon dioxide: < 0.1 %
The similarity among ancient civilizations of China, Egypt, and Greece with regard to sports is that they all organized athletic games that recurred annually.
I hope this helps! :)

This question is incomplete, here´s the complete question.
The super bowl is right around the corner and Bowen hotels is aquiver with anticipation. They'd like to price their rooms at their three city locations, next to the stadium, near the airport, and in the suburbs, as high as possible but still achieve 100% occupancy. The approach they should take to this opportunity is
:
- Yield management
- 360 units per month
- A chase production approach
- A tiered workforce
Answer: Yield management
Explanation:
Yield management, also called revenue management, is a variable pricing strategy usually applied in the hospitality business, such as air travel and several tourism-related enterprises. Yield management aims to produce maximum revenue from a fixed, perishable resource, like plane tickets, hotel room bookings, or advertising inventory. The goal is to obtain the highest possible profit by offering the right price at the right time.
<span>Yes, it's possible to hoist the child up.
Let's first determine the maximum amount of pull that the woman can exert. That will be the simple product of her weight and the coefficient of static friction with her shoes and the ground. So
0.8 * 190 = 152.
So far, so good, since 152 is greater than the boy's 80 lbs. But the cable rubs at the cliff edge and that means that the lady has to pull harder. Let's see how much harder.
There will be 80 lbs of tension on the cable, pressing against the cliff edge. So let's multiply by the coefficient of friction to get how much that is
0.2 * 80 = 16
So friction will take 16 lbs of effort to overcome. So the lady needs to pull with 80 + 16 = 96 lbs of force to move the boy. And since we've determined earlier that she can pull with up to 152 lbs of force, she can easily hoist the child up.</span>
