Absolutely not. You can have a piece of wood and water with the same dimensions, but dimensions Won't matter
Answer:
The potential energy can be given as
E = mgh. m is mass, g = acceleration due to gravity = 9.8m/s, h is the heigh, given as 100.0m
E = m x 9.8 x 100 = (980m)J
E = (980m)/10^9GJ = (0.000000980m)GJ to 3 significant figures
Explanation:
Hydroelectric dams exploit storage of gravitational potential energy. A mass, m, raised a height, h against gravity, g = 9.8 m/s², is given a potential energy E = mgh. The result will be in Joules if the input is expressed in meters, kilograms, and seconds (MKS, or SI units).
Answer:
B
Explanation:
Heated liquids at the earth's surface.
The atmosphere is made up of layers which vary in temperature and other characteristics.
<h3>Layers of the atmosphere</h3>
The atmosphere is divided into several layers. The atmosphere refers to the thin layer of air that lies above the earth crust. The following describes the layers of the atmosphere.
- The troposphere refers to the layer where weather changes largely occur and clouds form.
- The stratosphere has an average temperature of about 270 K (−3°C or 26.6°F). The ozone layer is found in the stratosphere.
- The temperature in he mesosphere is about − 85°C (− 120°F).
- The thermosphere has a temperature of 200° C (360° F). The ionosphere is found within the thermosphere.
