A circuit has a voltage drop of 60.0 V across a 120.0 resistor that carries a current of 0.500 A. What is the power conducted by the resistor? Use P = VI.

A.
7200 W

B.
60.0 W

C.
2.00 W

D.
30.0 W

Power, P = 30 W

Explanation:

We have,

Voltage drop of a circuit is 60 V

Resistance of the resistor is 120 ohms

Current across the circuit is 0.5 A

It is required to find the power conducted by the resistor. Power conducted by a resistor is given by :

V and I are voltage and current

So, the power conducted by the resistor is 30 watts.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
