Answer:
The underwater angles of refraction for the blue and red components of the light is 47.8° and 48.2°
Explanation:
Using the Snell's law
n1 * sin Ф1 = n2 sin Ф2
1 * sin 83 = n2 sin Ф2
Ф2 = 
Red light
n2 = 1.331
Ф2 = 
°
Blue light
n2 = 1.340
Ф2 = 
°
A. 90km/h = 25 m/s
W=1/2mv^2
=1/2* 650* 25^2
= 203125(J)
b. v’= 90-50= 40km/h
= 100/9 m/s
W=1/2mv^2
=1/2*650*(100/9)^2
= 40123,45679
never seen one although i guess the elegant answer is D) none of the mentioned posibilities
Answer:
p(a) * p(b) = .01923
p(b) = .01923 / .07692 = .2500
