Answer:

$c>d>f=a>b>e$

Explanation:

When a pair of medial has greater difference between the their individual refractive indices with respect to vacuum then it has a greater deviation between the refracted ray and the incident ray.

According to the Snell's law:

$\rm refractive\ index\ (n)=\frac{speed\ of\ light\ in\ the\ incident\ medium}{speed\ of\ light\ in\ the\ refracted\ medium}$

$n_1-n_2=1.33-1.00\\=0.33$

$n_2-n_1=1.46-1.33$

$=0.23$

$n_2-n_1=2.42-1.33\\=1.09$

$n_2-n_1=1.46-1.00\\=0.46$

$n_1-n_2=1.50-1.33\\=0.17$

$n_2-n_1=1.33-1.00\\=0.33$

$c>d>f=a>b>e$

Answer:

the answer is 30°

Explanation:

due to:

sin law of sines

$\frac{sin 90}{200} =\frac{sin\beta }{100}\\arcsin(100\frac{sin90}{200} )= 30°$

A swimmer does 3,560 J of work in 55 s. What is the swimmer’s power output? Round your answer to two significant figures. The po

Natasha2012 [34]

The value of the swimmer's power output is calculated by dividing the work done by the time it took for the work to be completed. From the given in this item,
P = 3560 J/ 55 s = 64.73 W
Rounding off to two significant figures will give us 65 W.
