A sailboat is traveling at a steady speed of 13 mph. The force of the wind pushing against the sail is _______ the opposing force of the water resistance.

To determine the force of the wind pushing against the sail compared to the opposing force of water resistance, you would need more specific information, such as the surface area of the sail, the angle of the sail in relation to the wind, and the coefficient of water resistance.

However, if we assume no external factors affecting the sailboat, we can make a basic assumption that the force of the wind pushing against the sail is approximately equal to the opposing force of water resistance. This is because when a sailboat is traveling at a steady speed, the forces acting on it must be balanced.

Keep in mind that this is a simplified explanation, and actual forces involved can vary depending on various factors. To precisely calculate these forces, you would need more detailed information about the sail, the boat, and the specific conditions it is sailing in.
