The signal to a speaker causes .5 amps of current. the signal level is increased to 2.5 amps. what is the gain, rounded to the nearest decibel?

Explanation:

It is given that,

The signal to a speaker causes 0.5 amps of current,

The signal level is increased to 2.5 amps,

We need to find the gain to the nearest decibel. The decibel gain formula of the speaker is given by :

db = 13.97 db

or

db = 14 db

So, the gain pf the speaker is 14 db. Hence, this is the required solution.

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
