If you are able to apply 200 Newtons (~45 lbs) to the 2 meter long handle, calculate the amount of work you could apply to lift a load.

Answer : The amount of current used  to warm your feet is, 0.1 A

Explanation :

To calculate the current we are using ohm's law:

where,

V = voltage = 9 V

I = current = ?

R = resistance = 90 Ω

Now put all the given values in the above formula, we get the current.

Therefore, the amount of current used  to warm your feet is, 0.1 A
