Answer:
6 pens for 36$ then 2 pencils for 2$ equal 38$
Step-by-step explanation:
x = 0.3333...
(multiply both sides by 10)
10x = 3.3333...
10x - x = 3.333... - 0.333...
9x = 3
x = 3/9 = 1/3
therefore, 0.3(3 bar) = 1/3
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
