Answer:
n = 1.76
Explanation:
According to the rule of ( n1 sin theta1 = n2 sin theta2 )
we know both angles so we insert them to the law and apply n1 = 1
so 1/2 = n2 sin 62 and we get the final answer

<span>Three-fourths of the illuminated side of the moon be visible
from Earth when the moon is at position-B. (choice-B)
Notice the particularly egregious screw-up on the drawing at the
"Third Quarter" position. There, the drawing shows the illuminated
side of the moon AWAY from the sun, and the dark side of the moon

Answer: 110km/h
100+10=110km/h
Explanation:
Motion is defined as a change of position. The frame of reference is usually assumed to be at rest. If one is sitting on a bus, the road appears to be moving backwards relative to the observer. If he/she now walks to the front of the bus, he has a speed relative to the earth which is now greater than that of the bus hence the answer.
Distance = velocity * time
1 hour and 15 minutes = 1.25 hours
25km/hr * 1.25 hours = 31.25km
