Answer:
Explanation:
By Snell's law we know at the left surface
now we have
now on the other surface we know that
angle of incidence =
so again we have
so we have
also we know that
By solving above equation we have
The green bars are called "error bars." They indicate the range of uncertainty that scientists have about the data on the graph.
(Note: Not all error bars are shown.)
Why do you think these error bars are smaller near the year 2000 than in the 1890s?

Answer:
The answer is
<h2>84.9 kPa</h2>Explanation:
Using Boyle's law to find the final pressure
That's
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final pressure
From the question
P1 = 115 kPa
V1 = 480 mL
V2 = 650 ml
So we have
We have the final answer as
<h3>84.9 kPa</h3>Hope this helps you
