Two sustainable ways in which businesses could assist school leavers

ASAP PLEASE HELP: What is convection and how does it contribute to making Death Valley so hot?

Norma-Jean [14]

Answer:

Death Valley’s crazy heats are caused by a combination of the lack of water, geography, and materials that make up the valley.

The average yearly rainfall in Death Valley is only 2 inches. This is less than many other deserts in the world, averaging around 10 inches of rain annually. This intense lack of water also creates a lack of plants in the area resulting in the expanses of sand in the valley open to constant heating by the sun.

Sea level in Death Valley

Driving into the valley you get to experience the geography of the environment, traveling from 1000 feet to 4000 feet above sea level and down to 100 feet below sea level. These mountain ranges you drive over top 4000 feet and surround the lowest point in the United States of 282 feet below sea level. This creates an interesting phenomenon of trapping the hot air within the valley.

Sand and rocks make up the valley floor which radiate a large amount of heat. However, because of the geography, this hot air cannot escape. Instead, the hot air rises along the valley walls, cools slightly and then falls back to the valley floor to be heated even more by the hot sand and low elevation air pressure. This concept of movement by heating and cooling is called convection and exists in many other life circumstances like the boiling of water or in a kitchen oven. Despite the movement of air and possibility of high winds, the winds do not do much to cool down the hikers in the valley because the wind is still very hot.

The heat can be so extreme that signs in the park advise turning off the air conditioning in certain areas to avoid overheating of cars, making the experience an even toastier one. Additionally, hiking is recommended only before 10am and with lots of water.

Despite the heat it is worth braving the heat to experience the truly unique views of Death Valley. This unique environment allows for rock formations, salt flats and expanses unlike anything else in the United States.

Of the $10$ kids in a chess club, $5$ are left-handed and $5$ are right-handed. the club holds a round-robin tournament in which

Nataliya [291]

The total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 is the fraction of all games at the tournament Anita plays.

<h3>How to carry out Permutation and Combination?</h3>

We are given that there are 5 girls and 5 boys in a chess club.

Thus, total games that girls play against a boy = 5×5 = 25

The number of games a girl play against another is the total number of games = 10

The number of games that are boy vs boy = 10

The number of games Boy vs Boy + Girl vs Girl + Boy vs Girl = 10 + 10 + 25 = 45

Fraction of the games that are boy vs boy = 10/45 = 2/9

If Anita is one of the club members, then Anita will have to play against 9 people at the tournament.

Total number of games = 45

Then the fraction of all games at the tournament Anita play the game.= 9/45 ⇒ 1/5

Thus, the total number of games a girl play against a boy is 25, the number of games a girl plays against a boy is 10, the fraction of the games are boy-versus-boy is 2/9, and 1/5 fraction of all games at the tournament Anita plays.
