Explanation:
V=C/n
Quartz: (3×10^8)/(1.54)=1.948×10^8 m/s
The higher the index of refraction the slower light will travel, so light will be slower in ruby.
<span>The water reduces friction between the surface you are standing on, and your feet.</span>
Explanation:
sexual reproduction provides genetic diversity because the sperms and the egg that are produced contain different combination of the genes than the parent organisms so in order to from a new organisms two gamete the sex cells sperm and egg must fuselage further mixing the gene to produce more genetic diversity
We know from the physics class that the time is simply the
distance divided by velocity:
time = distance / velocity
Substituting the given values and calculating for time:
time = 360 km / (72 km / hour)
time = 5 hours
<span>Therefore it takes the train 5 hours to arrive.</span>
