Plz will give which statement describes what happens when bret runs up a flight of stairs? his kinetic energy is destroyed. his potential energy decreases. his kinetic energy is converted into potential energy. his potential energy is converted into kinetic energy.

his kinetic energy is converted to potential energy

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.
