HELP ASAP PLEASE!!
Which of the following is most useful in the identification of a mineral?
A. size
b. weight
C. luster
D. length

C. luster

Explanation:

2 minerals could have the exact same length, size or weight, and be completely different minerals, so luster would be the most helpful.

Hope this helped!

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
