17. Challenge Express each answer in scientific notation in the units indicated. a. (1.26 X 104 kg) + (2.5 x 108 g) in kg
b. (7.06 g) + (1.2 x 10-kg) in kg
c. (4.39 x 105 kg) - (2.8 x 107g) in kg
d. (5.36 x 10-kg) – (7.40 x 10-2 kg) in g

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
