Question

The voltage V of an audio speaker can be represented by V= 4 sqrt P ​, where P is the power of the speaker. An engineer wants to design a speaker with 361 watts of power. What will the voltage​ be?

Answer 1

Answer:

$Voltage=76\ volts$

Step-by-step explanation:

$Given\ V=4\sqrt{P}\\\\where\ V\ is\ voltage\ and\ P\ is\ Power.$

$Here\ power\ is\ given\\\\P=361\ watts\\\\Substitute\ P\ in\ the\ given\ equation\\\\V=4\sqrt{P}\\\\V=4\sqrt{361}\\\\V=4\sqrt{19\times 19}\\\\V=4\times 19\\\\V=76\ volts$
