Answer:
About 16 times the energy of the second.
Explanation:
This can be explained thanks to the Stefan-Boltzmann law, which relates temperature directly to the amount of energy released by an object.
With this law in mind, the total energy radiated during 1 second from 1 square meter of any object, equals <em>a constant </em>(5.670374419 × 10−8 watt per meter2 per K4) times the temperature raised to the fourth power. the equation is:
E = σT4
Since the first star is twice as hot as the second, then the star won't produce twice the energy, but 16 times the energy due to the Stefan-Boltzmann constant. It's also important to know that this law only applies to blackbodies.
Answer:
Heating and Pressure
Explanation:
Sandstone forms from beds of sand laid down under the sea or in low-lying areas on the continents. As a bed of sand subsides into the earth's crust, usually pressed down by over-lying sediments, it is heated and compressed.
Answer:
Option (2)
Explanation:
Lithosphere refers to all the portions on earth where life exists. In simple words, the lithosphere is the layer that is comprised of the crust and a small portion of the upper mantle. Here the rocks are solid in nature.
Biosphere refers to the region that includes the land surfaces, hydrosphere as well as the atmosphere in which life exists and interacts. It occurs both above and below the earth's surface.
The rocks are disintegrated by both physical and chemical processes. These rocks when they are broken apart into smaller particles, then these sediments or rock particles are deposited in the soil that provides the necessary materials for the plants to grow.
Thus, the two spheres with which it interacts are the lithosphere and the biosphere.
Hence, the correct answer is option (2).
