What is a decimal that is equivalent to the fraction 7/10

In nuclear fission and fusion reactions mass is converted into energy. The average person in US uses around 100,000,000 J of ene

Answer:

a) The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) The energy that would be released if a 60 kg person were converted entirely into energy is $5.4\times 10^{18}$ Joules.

c) 180 years would this amount of energy support a population of 300 million.

Explanation:

a) Average energy consumed by single person of US = 100,000,000 J/year

Then 300 million US citizen will consume:

300 million = 300 × 1,000,000 = $3\times 10^8$

The yearly energy consumption for a US population :

$100,000,000 J/year\times 3\times 10^8=3\times 10^{16} J/year$

The yearly energy consumption for a US population of 300 million is $3\times 10^{16} J/year$

b) $E = m\times c^2$

E = Energy from converted mass of m

c = speed of light

Given mass of person = m = 60 kg

$E=60 kg\times (3\times 10^8 m/s)^2 = 5.4\times 10^{18} J$

c) Energy calculated in part (b) = $E=5.4\times 10^{18} J$

The yearly energy consumption for a US population of 300 million in an year = $3\times 10^{16} J/year$

Let the that would be supported by $5.4\times 10^{18}$ Joules of energy be x.

$x\times 3\times 10^{16} J/year=5.4\times 10^{18} J$

$x=\frac{5.4\times 10^{18} J}{3\times 10^{16} J/year}=180 years$

180 years would this amount of energy support a population of 300 million.

Kid Friendly Fun Facts about the Georgia Coastal Plain region. PLEASE HELP

muminat

Answer:

These here below are some Kid Friendly Fun Facts about the Georgia Coastal Plain region.

Explanation:

We can find the Coastal Plain Region in Georgia.

Did you know that Georgia is the 4th-state?
Did you know that Georgia has a nickname? It’s The Peach State! (Because the Cherokee indians used to grow this fruit here during the 17th-century.)

Here are some interesting facts about the Georgia Coastal Plain Region:

You can find it in the southern part of Georgia
It’s the largest geographical region of the state (60% of Georgia)
The region is divided into the Upper Plains and Lower Plains, but It’s just flat land - there are no steep hills here but savannahs (wild and green grass prairies)
The Upper Plains are really good for agriculture
The Lower Plains are along the coast and here is where the swamps are
During the Prehistoric period, the ocean covered the Coastal Plain Region
The climate is very humid! And it’s mild weather - winters are cool and summers are hot - but it rains a lot!
There’s a lot of water around: rivers, waterways, beaches, waterfalls, marshes and swamps
Georgia Coastal Plain has the largest swamp in North America: the Okefenokee Swamp, with 700 square miles
The swamps is the home to alligators
The most common animals living in this region are: deer, armadillos, rattlesnakes, woodpeckers, cranes, wild boar, squirrels and snapping turtles
There are plenty of cypress trees and orchards

People usually say that if you’re visiting Georgia and you miss The Plains, you miss visiting the whole state!
