Suppose that the life expectancy of a certain brand of nondefective light bulbs is normally distributed, with a mean life of 1100 hr and a standard deviation of 100 hr. if 80 comma 000 of these bulbs are produced, how many can be expected to last at least 1100 hr

50 inches should be the resultant vector

if they have a finite resultant

elctricity and magnet is conversion to it

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
