In summary, the net force on a snorkeler is the sum of all forces acting on them, including external and internal forces. It is calculated by adding together individual forces and is affected by factors such as water current, weight and buoyancy, and external forces from objects or other swimmers. The net force is important for a snorkeler as it determines their movement and acceleration in the water. A snorkeler can change the net force by adjusting their body position, using fins, or paddling against the current.

Homework Statement: What is the net force on the ocean snorkeler of Question 1 if the pressure inside her ear is 1.0 atm (=101.3 kPa)? An adult's eardrum has a typical diameter of 8.0 mm

Relevant Equations: P=F/A

Can someone help me understand what I did wrong when solving this problem?

You found the force on the eardrum due to the pressure inside the ear. Is there also a force due to pressure outside the ear?

1. What is the net force on a snorkeler's eardrum?

The net force on a snorkeler's eardrum is the sum of all the forces acting on the eardrum, including the pressure from the surrounding water and the tension from the eardrum itself.

2. How does the net force on a snorkeler's eardrum affect their ability to equalize?

The net force on a snorkeler's eardrum can make it more difficult for them to equalize, as it can create a pressure imbalance that makes it harder for the eardrum to move and equalize the pressure inside and outside the ear.

3. Can the net force on a snorkeler's eardrum cause damage?

Yes, if the net force is too great, it can cause damage to the eardrum, resulting in pain, hearing loss, or other ear injuries.

4. How can a snorkeler reduce the net force on their eardrum?

A snorkeler can reduce the net force on their eardrum by equalizing frequently and gently, using proper breathing techniques, and avoiding diving too deep or too quickly.

5. Are there any other factors that can affect the net force on a snorkeler's eardrum?

Yes, other factors such as the shape of the ear canal, the amount of earwax, and any existing ear conditions can also affect the net force on a snorkeler's eardrum and their ability to equalize.
