Which describes the impact that severe solar weather that continues for a long period of time has on satellite communications A. It will lengthen their time in space because they will need more time to collect data.

B. It will decrease the time it takes for messages to be relayed from Earth to satellites and vice versa.

C. It will increase the number of frequencies that satellites can use to communicate with Earth.

D. It will shorten the lifespans of the satellites because they will run out of fuel more quickly

Asun-sized star will spend most of its lifetime as a: white dwarf red giant protostar main-sequence star

Which is not a characteristic of a heat pump? a. it is used in air conditioners. b. it uses a refrigerant. c. it requires no work. d. it reverses the normal flow of thermal energy.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
