Nearly all of the energy that earth receives from the sun is used in photosynthesis-?
It is true that nearly all of the energy that earth receives from the sun is used in photosynthesis.
What portion of earth receives energy form the sun at any given time?
Since the Earth is a Spheroid shape, (not a true sphere) 50% of its surface is illuminated by the Sun, at any given moment.
According to classical physics what should happen as a filament in a light bulb gets hotter?
It should give off light of increasing energy- from red, to violet, and then into ultraviolet.This is because classical physics believed that the color of the light will correspond with the increasing of energy until it reaches ultraviolet. This is somewhat true as the color does correspond with the increasing energy but no matter how much energy there is, it will never reach ultraviolet. modern physics found that it will only stay white.
Is it true that the flow that transfers heat within a fluid is called a convection current?
In a convection current, heat flows with the heated molecules as they move around in the liquid or gas. In a solid, the heat transfers via condition
Does the land area or water area of Earth's surface absorb more solar energy?
Short Answer:Since there is so much more water than land, one expects that most of the solar energy absorbed by Earth is absorbed into the oceans. That is correct.Crudely, twice as much energy is absorbed by the oceans as the land since there is roughly a bit more than twice as much ocean as land.More Technical (Albedo):The characterization of how much solar energy is absorbed by a portion of the surface of the Earth is something called the albedo of the surface. Some surfaces, like dirt, forests and the ocean absorb most of the Sun's energy. Others, like Snow reflect most of it. Deserts are in between.The albedo of a surface is the fraction of light it reflects. (The term "reflects" does not mean like a mirror but rather means scatters or causes to light bounce back to distinguish "reflection" from the process where light is absorbed.) Normally, one refers to sunlight when quoting an albedo, but if a different or specific wavelength range is being considered, there are different values of the albedo that are defined for different parts of the electromagnetic spectrum.On average, the ocean surface has a low albedo meaning it absorbs most of the light that gets to it.The same is true for bare soil and most forests.Though the albedo is variable, 70 or 80 % of the light is absorbed.Desert areas typically have high albedos and can reflect most of the light.Most land areas are in an albedo range of 0.1 to 0.4, so 90% to 60% of the light is absorbed.The average albedo of the Earth is about 0.3, somewhat higher than typical of oceans or much of the land area primarily because of the contribution of clouds.Clouds reflect light very effectively, absorbing little.
When A wave transfers energy true or false?
The answer is true. The greater the energy the greater the amplitude.
Does light from the sun transfer energy to the earth?
Yes, it does.
True or false insulation minimizes undesirable energy transfers?
true
Does chemical energy travel from from the sun to earth and is transformed into light enerty by plants?
true
When light is absorbed light energy is transformed into stored energy true or false?
true
When light is absorber light energy is transformed into stored energy true or false?
true
What direction does heat trasfer?
Heat moves from a Hot surface to a cold surface in an atempt to acheive thermal equilibrium. This is true in most energy transfers High energy ALWAYS transfers to lower energy.
Is it true that a light bulb converts electrial energy into electromagnetic energy?
True. Light is a form of electromagnetic energy.
Is light energy transformed into stored energy when light is absorbed?
true
When light is absorbed is light energy transformed into stored energy?
true
When light is absorbed light energy is transformed into stores energy?
true
Is it true chemical energy travels from the sun to earth and is transformed into light energy by plants?
It's not chemical energy travelling from the sun, it's electromagnetic energy in the form of visible light. Chemical energy is found in things such as glucose, batteries etc.
