Intermolecular forces in water are greater than those in wood. APEX
Answer:

Explanation:
First, let's find the voltage through the resistor using ohm's law:

AC power as function of time can be calculated as:
(1)
Where:

Because of the problem doesn't give us additional information, let's assume:

Evaluating the equation (1) in t=3600 (Because 1h equal to 3600s):

Explanation:
Since I can only do this by observation, the elevation of F is approximately 850km and the elevation of B is 925km.
