What is the definition for Luminous and non luminous?
"Luminous" means emitting light (conveniently measured in units known as Lumens). Synonym would most often be "glowing".
What Diagram that represents high pitch?
A diagram that represents high pitch would typically show a waveform with a high frequency, indicating the rapid vibration of the sound wave. The wavelength would be shorter and the amplitude may be smaller compared to a low pitch diagram.
Which would be represented as a force arrow in a free-body diagram?
Any external or internal force acting on an object would be represented as a force arrow in a free-body diagram. For example, forces like gravity, friction, tension, and normal force would all be depicted with force arrows in a free-body diagram.
What is the sankey diagram for a radio?
A Sankey diagram for a radio would show the flow of energy from the power source to various components within the radio, such as the tuner, amplifier, and speakers. It would visually represent how energy is distributed and transformed within the radio system.
Can you draw a free body diagram for the car?
A free body diagram for a car would show the forces acting on the car, such as gravity, friction, and normal force. It would typically include arrows to represent the direction and magnitude of these forces.
What are the largest stars in the HR Diagram?
The largest stars would also be the brightest and that would put them near the top of the Hertzprung Russell diagram. The Sky Catalogue 2000.0 lists 50,071 stars of brightness down to magnitude 8.0. The brightest star is Rho Cassiopeiae with an absolute magnitude of -9.5, which is about 400,000 times more luminous than the Sun, and its spectrum is G2 like the Sun.
Which main sequence star would be least luminous- G1 G5 G9 F0 F3?
Among the given main sequence stars, the G9 star would be the least luminous. The classification indicates that G-type stars (like G1 and G5) are more luminous than G9 stars, and F-type stars (F0 and F3) are even more luminous than G-type stars. Therefore, as the spectral class moves from G1 to G9, the luminosity decreases, making G9 the least luminous option.
Which color star would be the most luminous?
The most luminous stars are typically blue stars, which are hotter and burn brighter than stars of other colors. They have surface temperatures exceeding 10,000 Kelvin and emit a significant amount of energy in the form of visible light and ultraviolet radiation. In contrast, red stars, which are cooler, emit less light and are generally less luminous. Therefore, blue stars are the most luminous among the different color classifications of stars.
How would you use luminous in a sentence?
i saw a luminous movement of water over white sand , and beyond that, a solid heavy blue.
On the Hertzburg-Russell diagram where would you find stars that are cool and dim?
Stars that are cool and dim would be found in the lower right corner of the Hertzsprung-Russell diagram, in the region known as the "lower right" or "lower main sequence." These stars have low luminosity and temperature compared to other stars on the diagram.
Why and how are various celestial objects luminous and non luminous?
Luminous objects are those which can produce or give out light of their own, while non-luminous objects cannot produce or give out their own light. Some examples of luminous objects would be the sun, stars, fireflies, glowworms and some deep sea fish Some examples of non-luminous objects would be the planets Mercury, Venus, Earth, Mars,Jupiter, Saturn, Uranus, Neptune and also Moons.
Why are old stars more luminous than young stars?
Well, it depends on if it's positioned closer to the earth or if they are about to supernova. And since the sun is the ONLY star in our solar system that would be the most luminous. =) hoped that helped.
Is a lighted candle an example of a luminous object?
Luminous objects are the objects that responsible for our vision and omit their own light. Stars, radium, LED, and sparks are some of example of artificial luminous object.
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
Why does a star called as a luminous?
"Luminous" in this context means "bright" - how much light (or how much energy in general) does the star emit. Note that stars look dim to us only because they are far away - some of them are actually several times brighter than our Sun, in absolute terms. That is, if you would see several stars, and our Sun, at a same standard distance, some stars would be dimmer, but others would be brighter, than our Sun.
When a lamp is turned off is it luminous or non-luminous?
If the bulb is switched off, then we would call it non-luminous.
Would the sun be more luminous if it were hotter?
Yes luminous actually for a star to get hotter.
