The HR diagram is based on brightness and temperature. If you want, you can search up the diagram. Most people classify the sides as Good For You and Bad for you, the bottom would be taste great and taste awful, but the answer is most likely brightness and temperature. Hope this helps you. :)
Explanation:
The vertical displacement of the wave is measured from the
equilibrium to the crest and is called the frequency.
crest to the trough and is called the amplitude.
trough to the trough and is called the wavelength.
equilibrium to the crest and is called the amplitude.

Answer:
False
Explanation:
Visible light is composed of radiation of wavelengths between 400 and 700 nm. The sensitivity of the human eye depends on the wavelength and has a maximum at 550 nm. Some people are able to perceive from 380 to 780 nm.
The electromagnetic energy in a particular wavelength λ (in a vacuum) has an associated frequency f and a photonic energy E. Thus, the electromagnetic spectrum can be expressed in terms of any of these three variables, which are related by equations.
Thus, high frequency electromagnetic waves have a short wavelength and high energy; Low frequency waves have a long wavelength and low energy.
To calculate the energy of a photon the Planck formula is used is E = h · v, where E is the energy, h the Planck constant and v the frequency (Hz or s-1). Where the frequency f is equal to the speed of the wave, divided by the wavelength λ
.
That said we can say that it is false because although the red light has a longer wavelength than the blue one, in turn it has a lower energy than the blue light.
Answer:
a) 
Explanation:
a) the cross-sectional area of the hose would be the square of radius times pi. And since the sectional radius is half of its diameter d. We can express the cross-sectional area A1 in term of diameter d1
Answer: The ice cube would float on top of the water and the rock would sink to the bottom.
Explanation: The ice cube has a smaller density than the rock which allows the ice cube to float but makes the rock sink to the bottom of the glass of water.
