Based on the law of conservation of energy, which statement is false?

the statement "energy is lost when machines don't work right' seems false because energy, again based from the law of conservation of energy, can neither be created nor destroyed; rather, it transforms from one form to another. therefore energy can never

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.

b.
