bonufazy [111]

Answer:

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

Explanation:

Mike Trout of the Los Angeles Angels has a contract worth $426,500,000

On the other side, you earn $100,000 per year.

To calculate the number of years it would take for you to earn what Mike Trout will earn from his contract, you must divide the amount Mike earned by the amount you earned during a year:

$426,500,000 ÷ $100,000 per year= 4,265

The number of years it would take you to earn what Mike Trout will earn on his contract is 4,265

based on distance to the nearest water well, which drilling site would pose the least risk of methane contamination?
Marysya12 [62]

Based on distance to the nearest water well, the drilling site that would pose the least risk of methane contamination would be the one farthest away from the water well.

Methane is a gas that is known to escape from the ground and rise up into the atmosphere. If the drilling site is too close to the water well, there is a greater risk that the methane could contaminate the water.

The atmosphere is the air that surrounds us. It is a mixture of gases, including nitrogen, oxygen, and carbon dioxide. The atmosphere protects us from the Sun's ultraviolet radiation and from the cold of space. It also contains the Earth's weather, which is caused by the Sun's energy.

How much energy is released when 20.0 g of water is cooled from 50°C to 30°C (Cwater= 4.18 J/ g*°C)
marissa [1.9K]

Answer:

1672 J

Explanation:

We are supposed to find out the energy released by water when cooled from 50° C to  30°C .

We have the relation that ,

H=msΔT

Information is given that s=4.18 J/ g*°C ,

m=20.0 g,

and ΔT is -20° C.

Hence by substituting we get,

H=-20*20*4.18

(minus symbol represents that energy is being released)

1672 J is release when water is cooled from 50° C to  30°C .
