Highest: Exosphere: 700 to 10,000 km (440 to 6,200 miles)
Thermosphere: 80 to 700 km (50 to 440 miles)
Mesosphere: 50 to 80 km (31 to 50 miles)
Stratosphere: 12 to 50 km (7 to 31 miles)
Lowest: Troposphere: 0 to 12 km (0 to 7 miles)
Explanation:
Don't see how "Little amounts of energy generated " is a cost, more of a less benefit. Harnessing tidal energy will by virtue of conservation of energy take energy out of the tidal system, so B
Answer:
Preparation of Bases
By the direct union of a metal with oxygen Some metals when heated in air or oxygen form the oxides of the metals. ... By the action of water or steam on some active metals Some active metals like sodium and potassium react with cold water to form hydroxides with the evolution of hydrogen gas.
Answer:
0.25 mm> 0.50 mm > 0.75 mm> 1mm> 1.25 mm
Explanation:
Capillary movement involves the movement of liquid up through a capillary tube.
Looking at the question, we can see all the various diameters of the capillary tube are involved.
Note that, that the narrower the diameter of the capillary tube, the better the capillary action of the liquid (the liquid rises more now than then).
The answer should be A, has more energy than it does in the ground state. De-excitation is removing electrons, so excitation would be adding more in to make it more stable. The ground state is what is considerd stable.
ANSWER: A
