The energy stored on a capacitor is of type potencial, therfore depends on the capacity to "store" energy. Inthe case of the capacitor, it stores charge (Q), and the equations you use to calculate it are:
In this case we know V and C, therefore we use the last expression:
r=2.743
Answer:
Answer = 3.16m
Explanation:
The concept applied here is the relationship between intensity and sound level. the intensity I of a sound wave is the average rate per unit area at which energy is transferred.
I = P/A
I = intensity
A = Area
The intensity of a sound wave can also be expressed in terms of the decibel scale. DB is the abbreviation for decibel which is the unit of sound level this was named after Alexander Graham bell whose work on this aspect was recognized.
The step by step calculation and necessary derivations is a shown in the attachment.
