Solution

The pressure experienced by a swimmer in water is due to the weight of the water above them. This pressure increases with depth because as you go deeper, there is more water above you, and therefore more weight pressing down.

Here are the steps to understand this:

  1. Pressure in fluids, such as water, is calculated by the equation P = ρgh, where P is the pressure, ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid above the point in question.

  2. When a swimmer is closer to the surface, the height (h) of the water above them is less. According to the equation, if h is smaller, the pressure (P) is also smaller.

  3. Therefore, the closer to the surface a swimmer swims, the lower the pressure on the swimmer. This is because there is less water above them to exert pressure.

  4. Conversely, the deeper a swimmer goes, the greater the pressure, because there is more water above them to exert pressure.

So, the depth at which a swimmer swims directly affects the pressure they experience due to the weight of the water above them.

A swimmer is towed through the water firstly while lying in a prone position on the water surface, then in a prone position but submerged under the water surface (assume the swimmer maintains the same horizontal position and is towed at the same speed in both situations). The person towing the swimmer would usually need to apply the greatest force to move the swimmer through the water in which situation:Question 17Answera.the prone position on the water surface and pulled quickly because, in this position, the swimmer has a higher wave drag than when submergedb.the prone position on the water surface because in this position, the swimmer has a higher surface area exposed to two types of fluid than when submerged, which increases form dragc.the submerged prone position and pulled quickly because, in this position, the swimmer has a less streamlined body position compared to when on the water surface, which increases form dragd.the submerged prone position and pulled quickly because, in this position, the swimmer has a higher surface area exposed to the flow compared to when on the water surface, which increases surface drage.the same force would be applied to the swimmer in a prone position on the water surface and when submerged to move them at the same velocity through the water. This is because there is the same amount of form drag in both situations.
