An escalator that takes 1.2 MJ every minute has a power output of 1200 kW.
An escalator used to lift people up from one floor to another, exerts a work (w) of 1.2 MJ in 1 minute (t).
In physics, power (P) is the amount of energy (w) transferred or converted per unit time (t).
We can convert 1.2 × 10⁶ W to kW using the conversion factor 1 kW = 1000 W.
An escalator that takes 1.2 MJ every minute has a power output of 1200 kW.

Answer:
4.35x10¹⁷s is the age of the universe
Explanation:
The age of the universe is 13.8 billion years.
As we know, 1 billion years = 1x10⁹years
13.8 billion years * (1x10⁹years/ 1 billion years) = 13.8x10⁹ years.
As 1 year = 3.154x10⁷ seconds, 13.8x10⁹ years are:
13.8x10⁹ years * (3.154x10⁷ seconds / 1 year) =
<h3>4.35x10¹⁷s is the age of the universe</h3>
