Explanation:

Energy is the ability to cause change; power is directly proportional to energy and its the rate energy is utilized.

Power=energy/time.

First we need to calculate the total energy used which is equal to the total power utilized.

E(total)= P( total) = 1.4W × 0.070 s =0.098J

When people smoke, carbon monoxide is released into the air. In a room of volume 70 m3, air containing 5% carbon monoxide is int
KonstantinChe [14]

Answer:

\frac {dQ}{dt}=0.0001-\frac {Q}{70}\times 0.002

Explanation:

Given that the volume is 70\ m^3

The air flows (F) at the rate of 0.002\ m^3/min. The concentration of carbon monoxide in the air is 5%.

Let Q be the amount of the carbon monoxide present in the room at time t. then,

\frac {dQ}{dt}=Rate\ of\ Q_{in}-Rate\ of\ Q_{out}

Also,

Rate\ of\ Q_{in}=5\%\ of\ 0.002=0.0001

Rate\ of\ Q_{out}=\frac {Q}{70}\times 0.002

Thus,

\frac {dQ}{dt}=0.0001-\frac {Q}{70}\times 0.002
