Answer:
Explanation:
<u>Series</u>
If two 1.5 volt batteries are connected positive to negative, the total voltage is 3.0 volt. This is because batteries in series produce a voltage equal to the number of batteries multiplied by the voltage of each individual battery
<u>Parallel</u>
The word parallel means "alongside each other". When batteries are placed in parallel all the positive terminals are joined together with a single wire to one part of the circuit, and all the negative terminals are joined with a single wire to the rest of the circuit
Remember the voltage increases when batteries are in series, but with batteries in parallel this is not the case. When two or more batteries are placed in parallel, the voltage in the circuit is the same as each individual battery. That is two, three, four or more 1.5 volt batteries in parallel will produce a voltage of 1.5 Volts
Electric currents travel and static electricity just stays and doesn't move
To solve this problem it is necessary to apply the concepts related to Sound Intensity. The unit most used in the logarithmic scale is the decibel and mathematically this is expressed as
Where,
= Sound intensity level in decibels
I = Acoustic intensity on the linear scale
Hearing threshold
According to the values, the total intensity is 32 times the linear intensity and the value in decibels is 83dB
So:
Therefore the sound intensity due to one person is 67.948dB
