What is the surface area temp of the star acturus?
Wikipedia lists a surface temperature of 4300 K.
What is the surfqace area of a cylinder?
It is the surface area of the two ends plus the surface area of the curved surface. Surface area of each end is pir2 Surface area of the curved surface is 2pirh Total surface area = 2pir2 + 2pirh
How can you obtain a cell's ratio of surface area to volume?
To obtain the ratio of surface area to volume, divide the surface area by the volume.
Why sphere has minimum surface area for given volume?
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . . If it is known is N-face surface area of ​​the body, there are N +1 is smaller the surface area of ​​the surface When N tends to infinity for a long time, Serve the sphere surface. ------mecose
What is the mathematical name for surface area?
it is still surface area
What is the surface area temp of the star acturus?
Wikipedia lists a surface temperature of 4300 K.
What color does a star turn when its surface area increases greatly?
Orange, red, or blue.
What factors affect the color of a star?
The temperature affects the color of a star.
What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Suppose there are two stars A and B with the same luminosity. If star A is larger then star B then we can conclude that?
A The temperature of star B is lower B The temperature of star A is lower C Star A is more massive D Star B is more massive E Not enough information to conclude anything
Is the size of a star the only factor that setermines its absolute magnitude?
No. I assume you mean the star's diameter. The area is proportional to the square of the area - so the bigger the star, the brighter it will be - other things being equal. However, the star's surface temperature also affects its brightness.
Why does the luminosity of the star depend on both its radius and its temperature?
The bigger the star's radius, the greater its surface area which emits the light. The bigger the temperature, the more luminous is the light the star is emitting.
What affects the luminosity of stars?
There are 2 main factors: the size of the star and its surface temperature. A larger size means a larger surface area to emit light. A higher surface temperature increases the energy emitted. Seen from Earth, the brightness of a star depends on how far away the star is as well as its actual luminosity.
If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
Why does an expanding giant star become more luminous?
As a giant star expands, its surface area increases, allowing more energy to escape from its core. This increased surface area results in the star appearing more luminous. Additionally, the expansion causes the outer layers of the star to become less dense, which allows more light to escape and contribute to its overall brightness.
What is a surface of a star?
the surface is wierd
What is the temperature of an expanding star?
The temperature of an expanding star can vary depending on its size and stage of evolution. Generally, as a star expands, its surface temperature decreases due to the increased surface area over which the energy is distributed. However, the core temperature of the star can increase as it undergoes fusion reactions.
