Answer:
Hotter star is more luminous.
Explanation:
A blackbody is an object that absorbs all the radiation incident on it. It does not reflect or let the radiation pass through it.
When the radiations are absorbed, the blackbody heats up. This results in the emission of radiation by the blockbody.
The amount of radiation the black body emits, depends upon the temperature of the blackbody. Therefore, greater the temperature of the blackbody, more the emitted radiation.
A star is very similar to a blackbody. So, if two stars are compared, then the hotter star will emit more light as compared to the cooler star.
Therefore, the hotter star will be more luminous than the cooler star.
Each rectangle is (18cm)(10cm)=180 square cm.
180 square cm/45 square cm=4. she cuts four triangles from each rectangle
(4 patches/rectangle)(32 rectangles)=128 patches
Answer=128 patches
Answer:
C. The greater an element's density, the smaller the amount of it found in the crust
Explanation:
The layering of the Earth happened because of the different densities of the elements from which it was made. The denser elements started to sink deeper, the elements with medium density occupied the central part, and the elements with the smallest density remained at the surface. This resulted in the formation of the three basic layers of the Earth, core, mantle and crust. The core is composed of the densest elements, the mantle of the ones with medium density, and the crust from the ones with smallest density.
The answer is places and regions
