Hakim used 18000J of energy to climb up to the top of a building in 10 mins. calculate the power he developed in climbing up to the top of the building?

P = 30 W

Explanation: To solve for Power we will use the formula P = E / t or energy per unit time which is in seconds.

First convert 10 minutes to seconds

10 mins x 60 s / 1 min = 600 s

P = 18000 J / 600 s

= 30 W

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.
