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.
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
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.
Indicate whether the following statement is True or False Light bulbs are non-directional devices?
True; the light shines outward in all directions.
