What does an H-R diagram compare?
An H-R diagram compares the luminosity (brightness) of stars with their surface temperature. It helps classify stars based on their temperature and luminosity, allowing astronomers to study their characteristics and evolution.
What is the H R diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
What is h r diagram?
The H-R diagram is a graphical tool used to classify stars according to color, temperature, spectral type, luminosity, and evolutionary stage. H-R stands for Hertzsprung-Russell.
What range of the H R diagram is your Sun placed in because its temperature and absolute magnitude are average?
Main Sequence
Does the H-R diagram classify stars by the amount of heat they create?
The Hertzsprung-Russell diagram (H-R diagram) is a graph of stars showing the stars' luminosities or absolute magnitude versus their spectral type which is related to their effective temperature.
What are the release dates for Doradus - 2014?
Doradus - 2014 was released on: USA: 3 March 2014
What is the recommended R-value for garage insulation to ensure energy efficiency and temperature control?
The recommended R-value for garage insulation to ensure energy efficiency and temperature control is R-13 to R-19.
What is the saturation temperature of r-410a at 38 psig?
The saturation temperature of R-410A at 38 psig is approximately 18.5°C or 65.3°F.
What are the two temperature scales we use to measure temperature?
F, R, C, and K.
IS S Doradus going to exsplode?
Probably. It is an extremely bright star (a very high absolute magnitude), with a high mass, and such stars tend to end up as a supernova.
Application of differential equation in temperature?
Newton's equation of cooling is a differential equation. If K is the temperature of a body at time t, then dK/dt = -r*(K - Kamb) where Kamb is the temperature of the surrounding, and r is a positive constant.
What is condensing temperature for a head pressure of 175 psig for an R-12 system?
The condensing temperature for an R-12 system with a head pressure of 175 psig would be approximately 119°F. This is based on typical saturation temperature-pressure relationship for R-12 refrigerant.
In the equine business what does T P R mean?
T= Temperature P= Pulse R= Respiration
What are the two temperature scales that r used?
Celsius and Fahrenheit
What is the evaporation temperature of R-134a at 0 psig?
The evaporation temperature of R-134a at 0 psig (or atmospheric pressure) is around -26.2°C (or -15.16°F).
What is the equation for temperature coefficient of resistance?
R= R0 * [1 + rho( t2-t1 ) ] so from this equation , rho= R-R0/[R0(t2-t1)] where rho- coefficient of resisivity R-resistance at any time t R0- resistance at 00C t2-final temperature t1-initial temperature
Biggest star in the world?
There are no stars in the world. _________________________ However, the hypergiant star S Doradus may be the brightest star so far observed. Because the center of the galaxy is sheathed in nebulous gas clouds surrounding the massive black hole in the center of the Milky Way, there isn't any way (so far!) to observe stars on the other side of our own galaxy. S Doradus is the brightest star in the Large Magellanic Cloud.
