Kavita, Mahima and Shreya were doing an experiment in which water was to be heated in a beaker. Kavita chooses to heat the water using the innermost part of the flame, Mahima chooses the yellow part and Shreya chooses the outermost part of the flame. The beaker in which the water will be heated at the earliest is of

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.
