A spherical shell has inner radius Rin and outer radiusRout. The shell contains total charge Q, uniformly distributed. The interior of the shell is empty of chargeand matter. a. Find the electric field outside the shell, r ≤ Rout.
b. Find the electric field in the interior of the shell, r ≤ Rin.
c. Find the electric field within the shell, Rin ≤ r ≤ Rout.
d. Show that your solutions match at both the inner and outerboundaries.
e. Draw a graph of E versus r.

A3.9 g aluminum foil ball with a charge of +4.1×10−9 c is suspended on a string in a uniform horizontal e⃗ field. the string deviates to the right and makes an angle of 30∘ with the vertical. part a part complete what information about the e⃗ field can you determine for this situation? what information about the field can you determine for this situation? only the magnitude of e⃗ only the direction of e⃗ both the magnitude and the direction of e⃗ none of the above previous answers correct part b determine the magnitude of the electric field. express your answer with the appropriate units. e e = nothing nothing request answer part c determine the direction of the electric field. determine the direction of the electric field. to the right to the left away from you toward you

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.
