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, .
b . Find the electric field in the interior of the shell, .
c. Find the electric field within the shell, .
d. Show that your solutions match at both the inner and outerboundaries.
e. Draw a graph of E versus r.

Ajet plane has a sound level of 120 db at a distance of 60 m. what is the q23. sound level at a distance of 6.0 km? (60)2 (6000)? om solution 80db db, hint: 16x assume ultrasound waves travel through the body of an animal at 1540 q24. m/s. if a 30,000 hz signal were reflected off a portion of a heart which was moving toward the source at 3 m/s, what frequency signal would return to the stationary source? solution 30.117hz

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
