Answer: 45° and speed of light in prism 2×10⁸m/s
Step-by-step explanation:
The minimum deviation of the equilateral glass prism will form 60° angle.
So angle of incidence = 3/4×60
= 3 ×15
= 45°
Minimum deviation = δmin
= 30
After finding the value of μ using prism law
μ = 1.41
Speed of light will be 2×10⁸m/s

Yes, because 10 x 10 x 10 x 10 x 10 (which equals 10^5) is equal to 100,000.
Remember, 10 to the power of anything (like 8, 5, or 9) just means that you have to count out however many zeros the exponent tells you to, which in this case, is five.

Part A: 1083.5 ft
Part B: 1921.37 ft
Part C: 66.93°

Answer: −3(5c+4)(5c−1)
Step-by-step explanation:
1. Find the Greatest Common Factor (GCF).
GCF=3
2. Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3(75c^2/3+45c/3−12/3)
3. Simplify each term in parentheses.
−3(25c^2+15c−4)
4. Split the second term in 25c2+15c−4 into two terms.
−3(25c^2+20c−5c−4)
5. Factor out common terms in the first two terms, then in the last two terms.
−3(5c(5c+4)−(5c+4))
6. Factor out the common term 5c+4
−3(5c+4)(5c−1)
