Answer:

from formula,

n = <u>speed</u><u> </u><u>of</u><u> </u><u>light</u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>

speed of light in medium

In Silica,

1.44 = (3e8m/s)/v

v= (3e8m/s)/1.44

v = 20.83e7m/s

v = 20.8 × 10^7m/s.

Light travels in silica at 20.8 × 10^7 m/s.

Answer:

2.08 x 108 m/s

The speed of light in this fiber is found to be v = c/n = (3.00 x 108 m/s)/(1.44) = 2.08 x 108 m/s.

The balanced equation for photosynthesis is shown below.
klio [65]
The true answer is: It's conserved because the total number of H atoms on each side is 12.
the first two answer is wrong because it's conserved not as mentioned, It's not conserved.

and the last one also wrong because the total number of O atoms are equal at the two sides but not equal 2.
