I would say Conduction because you are touching the cookie sheet, even though it is hot (so heat) you are physically touching it so it would not be radiation
The electromagnetic spectrum includes a continuous spectrum of wavelengths that include:
Radio waves, microwaves, infrared light, visible, ultraviolet, X-rays, gamma rays
The wavelength decreases from radio waves to gamma rays, whereas the energy increases along the same direction.
In the given example, radio waves have a lower energy and higher wavelength than visible light. The latter can be perceived by the human eye, whereas radio waves are not visible to the human eye.
1) They have colors = visible light
2) They can travel in a vacuum = both
3) They have energy = both
4) They’re used to learn about dust and gas clouds = radio waves
5) They’re used to find the temperature of stars = visible light
6)They’re invisible = radio waves
Answer:
<h2>false</h2>
Explanation:
because Oxalic acid is present in spinach
<h2>MARK ME AS BRAINLIST</h2>
Answer:
Explanation:
Given
Wavelength of radiation 
We know Energy of wave with wavelength 
is given by
where h=Planck's constant
c=velocity of light
=wavelength of wave
Hence the energy of the wave with wavelength 784 m is 
Answer:
A radiator emitting warm air and drawing in cool air is an example of convection current
Explanation:
I am guessing you meant "A radiator emitting warm air and drawing in cool air'
