Answer:
t=17.61 years.
Explanation:
Given that
Reserve of energy = 10,000 EJ
Energy used by human = 18 TW
We know that
So
Lets t time after energy will be exhaust
So
We know that
1 year = 365 days
1 year = 365 x 24 hr
1 year = 365 x 24 x 3600 s
So
t=17.61 years.

<h3>What is playa?</h3>
Playas are flat-bottomed depressions that are sometimes surrounded by water which it slowly seeps into the groundwater system or vaporizes into the atmosphere. As a result, salt, sand, and mud are deposited along the depression's bottom and around its edges.
Some key feature of playa are-
- Playas are also known as pans, flats, or dry lakes.
- They are typically found in inner desert watersheds and close to coasts in arid and semi-arid regions.
- The flattest recorded landforms are playas. Typically, their gradients are less than 0.2 meters per kilometer.
- Many kilometers of surface may be submerged when only a few centimeters of water are added.
- The nearly flawless flatness that is so distinctive of these dry region landforms is developed and maintained by the process of flooding.
- The middle, level basins of arid plains are called playas. They need drainage from the inside to a place where evaporation far outweighs intake.
- A playa lake arises when the area is inundated, concentrating salts and fine-grained debris.
- Playa terminology is somewhat confusing due to the abundance of regional names.
