If the index of refraction of glass is 1.5, calculate the velocity of light in glass. m/s light always travels as 3.00 x 108 m/s 4.5 x 108 5.0x 10-9 2.0 x 108

speed of light in medium is 199,861.6 km/s

Aye, so the first answer is also correct but it’s just not solved all the way.

199,861.6 KILOMETERS per second means that you just have to multiply that by 1,000 to change it into meters. This will get you 199,861,600 meters.

Last thing you need to do it change it into scientific notation which would round the number to 200,000,000 which would translate to 2.0 x 10^8.

The answer is 2.0 x 10^8

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
