Earth can be considered as a spherical capacitor with two plates, where the negative plate is the surface of earth and the positive plate is the bottom of the ionosphere, which is located at an altitude of approximately 70 km. the potential difference between earth's surface and the ionosphere is about 350,000 v. the radius of the earth is 6,378 km. calculate the capacitance of the system.

part 1: describe the mass and the surface temperature of dwarf stars.

part 2: explain using complete sentences where on the hr diagram you would expect to find a dwarf star based on its physical properties.

part 1: the mass of a dwarf star is very small and the surface temperature of dwarf stars are high and they have the lowest absolute brightness.

part 2: on the hr diagram you would expect to find a dwarf star based on its physical properties at an absolute brightness of -2 to -4

hope this
