How is it possible for white dwarfs to have a lower luminosity than the sun even though it is much cooler?

Biology
1 answer:
ratelena [41]3 years ago
4 0

Answer:

White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.

Explanation:

As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.

True or false the water table is the lower surface of a aquifer
8090 [49]

Answer:

True

Explanation:

Groundwater is the water present beneath Earth's surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
