Water is always on the move. Rain falling today may have been water in a distant ocean days before. And the water you see in a river or stream may have been snow on a high mountaintop. Water is in the atmosphere, on the land, in the ocean, and underground. It moves from place to place through the water cycle.
Where's the water?
There are about 1.4 billion km3 of water (336 million mi3 of water) on Earth. That includes liquid water in the ocean, lakes, and rivers. It includes frozen water in snow, ice, and glaciers, and water that’s underground in soils and rocks. It includes the water that’s in the atmosphere as clouds and vapor.
If you could put all that water together – like a gigantic water drop – it would be 1,500 kilometers (930 miles) across.
<h3><u>Answer;</u></h3>
All the above
-street lights
-businesses
- Homes, etc
<h3><u>Explanation; </u></h3>
- Nuclear energy comes from splitting atoms in a reactor to heat water into steam, turn a turbine and generate electricity.
- Nuclear reactions are used to release nuclear energy that generate heat, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.
- Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
- Nuclear energy may be used in a wide variety of fields as it generates high levels of electricity without causing damage to our environment and atmosphere.
Variables we know:
t = 8 seconds
Vi = 0 m/s
g = -9.81
Δy = ?
Vf = ?
Equation we will be using to solve for Vf: Vf = Vi + gt
Steps to solve:
Vf = (0) + (-9.81)(8)
Vf = -78.48 m/s
Hope this helps!! :)
