How can you use the position-time graphs for two in-line skaters to determine if and when one in-line skater will pass the other
Jet001 [13]

Explanation:

Position-time graphs measure/express the position of a skater over time relative to the start or finish of the race (depends on how it is used). Note: are the skaters in line vertically or horizontally? Like is one directly behind the other or are they next to each other?

If the two skaters are in line horizontally with each other, then their position will be the same relative to the start or finish of the race. This means if one passes the other one, the position would be different for all times after they pass. On the graph, it would look like one single line at the start (as position is same) which splits into 2 (representing the new difference in position due to 1 passing the other.

If the two skaters are in line vertically, their lines on the graph will appear parallel to each other (assuming they are going same speed) because the position is changing at the same rate, one is just reaching the same point after the other. If the skater behind overtakes the one in front. The lines on the graph will cross and continue either in parallel but with the other line on top to represent the moment where their position is the same right before they pass and after, where the second skater is now in front.

Hope this helped!

Mountain Airlines has annual operating revenues of less than $75 million with hubs in Denver and Salt Lake City. This airline wo
Vladimir79 [104]

Answer:

Regional carrier                  

Explanation:

Like in many countries, in United States, the airlines are either privately owned or publicly owned. In the United States, airlines are categorized in to major airline carriers, national airline carriers and regional airline carriers by the revenue it generates.

Accordingly, if an airline generates revenue more than 1 billion dollar in a year, it falls in the Major Airline carriers category.

It the revenue generated by the airline is within the range of $100 million to $1 billion, then it is called National airline carriers.

However, if the revenue is less than 100 million dollar for a year, then that airline is called a Regional airline carrier.

In the context, as the revenue generated by the Mountain Airlines is less than  75 million dollar, it is called Regional carrier.

Hence, the answer is --- Regional carrier

Monochromatic electromagnetic radiation illuminates an area of a surface. The electric and magnetic fields of the waves are then
emmasim [6.3K]

Answer:

c) True. factor four

Explanation:

The energy density of an electromagnetic wave is given by

             u = ½ ε₀ E² = B² / 2μ₀

Where ε₀ is the dielectric constant and μ₀ the magnetic permittivity.

Let's apply this equation to the present case

 

If we double the electro field

               E ’= 2 E₀

               u’= ½  ε₀ (2E₀)²

               u’= ½ ε₀ Eo² 4

               u’= 4 u₀

Therefore the energy is multiplied by four

Let's check the answers

a) False

b) False

c) True

d) False

e) False
