The magnetic field within a long, straight solenoid with a circular cross section and radius r is increasing at a rate of db/dt. ( include pictures and graphs)

a) what is the rate of change of flux through a circle with radius r1 inside the solenoid, normal to the axis of the solenoid, and with center on the solenoid axis?

b) find the magnitude of the induced electric field inside the solenoid, at a distance r1 from its axis.

c) what is the magnitude of the induced electric field outside the solenoid, at a distance r2 from the axis?

d) what is the magnitude of the induced emf in a circular turn of radius r/2 that has its center on the solenoid axis?

e) what is the magnitude of the induced emf if the radius in part d) is r?

f) what is the induced emf if the radius in part d is 2r?

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

as technology advances, new experiments often expose problems in accepted theories. c

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.

b. a lightning bug, plug of grass, and a worm
