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.
When A wave transfers energy true or false?
True. Waves transfer energy from one place to another by oscillating particles in a medium or by creating electromagnetic fields in a vacuum.
Is A wave transfers energy true or false?
True. A wave transfers energy by propagating through a medium or space. Energy is carried by the oscillations of particles or fields in the wave, which can be in the form of mechanical waves like sound waves, electromagnetic waves like light, or other types of waves.
Does light from the sun transfer energy to the earth?
Yes, it does.
Does chemical energy travel from from the sun to earth and is transformed into light enerty by plants?
true
True or false the ultimate source of energy for physical life on earth is the sun?
True. The sun is the ultimate source of energy for physical life on Earth as it provides sunlight for photosynthesis, which is the process by which plants convert light energy into chemical energy that is then used by animals as a source of food and energy.
When light is absorber light energy is transformed into stored energy true or false?
true
Is it true that a light bulb converts electrial energy into electromagnetic energy?
True. Light is a form of electromagnetic energy.
Say true or false. light energy is invisible?
True. Light energy is electromagnetic radiation that is invisible to the naked eye.
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 stored energy true or false?
True. When light is absorbed by a substance, the light energy is converted into stored energy within the molecules of the substance. This stored energy can then be used for various processes such as chemical reactions or heat production.
Is it true that A light bulb converts electrical energy into both heat and light energy.?
Yes, it's true. When a light bulb is turned on, most of the electrical energy is converted into heat, but some of it is also converted into light energy. This is what allows the light bulb to produce light.
