Answer:
The sound level of 41 singers is approximately 79.52 dB.
Explanation:
As the sound level is given as 63.4 dB
The Intensity to Sound level relation is given as
Here β is given as 63.4 dB
I is to be calculated for 1 singer
I_o is constant as 10⁻¹²
So the equation is given as
Now as there are 41 singers so their I is given as
Now the value of sound level is given as
Answer:
The current is the ratio of the potential difference and the resistance. It is represented as (I). The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).
Explanation: so 9/3=3 current is 3 ampere
The current can be found from Ohm's Law, V = IR. The V is the battery voltage, so if R can be determined then the current can be calculated.
