Question

What is the electric potential a distance r from the center if r > b? [(infinity) = 0.](formula) Find the equivalent resistance between points a and b if R = 10 Ohm. A person is looking at a spherical mirror and sees his face upright and diminished, what kind of mirror is this, concave or convex? What kind of image is this real or virtual? Write formulas for a. beta^+ -decay of^133_56 Ba b. Electron capture by^133_56 Ba c. alpha-decay of^236_94Pu

Answer 1

6ccording to the HOMEWORKLIB RULES I am allowed to answer only 1 question at a time .

3) Here R =10 Ohms

R1 = 10 + 10 = 20 OHMS

R2 = 10 + 10 = 20 OHMS

R(eq) = ( 1/R1 + 1/R2 ) ^-1 = 10 OHMS

R3 = ( 1/10 + 1/10 ) ^-1 = 5 OHMS

R(total ) = ( 1/10 + 1/5 ) ^-1 = 3.33334 ohms ===========================ANSWER)
