Expense of running an electric appliance for 2 hours is 1.32 $.

Explanation:

Power is defined as the energy consumed or converted or heat transferred per unit time. Its actually equationally described as energy divided by the time.

In the question, the appliance is consuming electricity at 110 volts and 30 amps.

So the power consumed in 1 hour = 110 \times 30  = 3300 watts.

So the energy consumed in 2 hours = 3300 watts \times 2 hours = 6600 watt hours. =6.6 kilowatt hours.

So expense at the rate of 0.2 $ per hour = 6.6  \times 0.2 $ = 1.32 $.

Explanation:

Ions DO NOT move in Ion channels by simple diffusion because most ion channels can be:

I) selective of ions pass through it.

II) operating on a "open and close" principle. Where it opens or close on its own accord OR does so ONLY when induced by a specific influence like change in voltage of ion channels.

IN ADDITION to the concentration gradient, ELECTRICAL GRADIENTS (change in membrane voltage) affects the movement of ions through ion channels
