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

180 °- 121°
= 59°
the answer is 59°
The HA Theorem is a special case of the AAS postulate.
Answer:
A
Step-by-step explanation:
The reason it's A is because to make the ratio 1:1 you need to have a whole number you can't have half a pencil or pen, so what you need to do is add 22 and 96 and divide you should get 59, but if you add 23 to 96 and divide you get 59.5 and you can't have half a pencil (you can but that's not what were looking for). So in problems like this add and then divide by 2 and choose whole numbers because you can't have half in ratios cause that won't give the correct answer.
Answer:
a= 3
b=-4
c=-8
Step-by-step explanation:
3x²=4x+8
since the 4X is positive it will cross the equal sign and become negative and the same goes for 8,and this will leave nothing on the right of the equal sign therefore it will become 0
3x²-4x- 8= 0
the above equation is now in the form required
ax²+bx+c=0
so substitute the values according and u will see that a= 3
b=-4 and c=-8
hope this helps
