Answer: We can see the moon during the day for the same reason we see the moon at night. The surface of the moon is reflecting the sun's light into our eyes
Explanation:
Answer:
The speed of light becomes slower in denser medium which is water in this case.
Explanation:
We know the lens law of Refraction which states
Refractive index of second medium /Refractive index of the first medium
= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)
When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.
When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.

Answer:
0.625 kg
Explanation:
Since 90.6 is 3 half-lives from 30.2 (90.6/30.2 = 3) , divide the initial mass of the sample by 2, and divide that quotient by 2, and divide THAT quotient by 2 to determine how much remains after 3 half-lives.
