Question 1

What is the main reason for the instability of an iceberg during underwater melting?

  • Increase in visible height
  • Shifting center of buoyancy
  • Decrease in water temperature

💡 Hint: Think about the submerged part of the iceberg.

Question 2

True or False: A higher metacentric height indicates better stability in floating objects.

  • True
  • False

💡 Hint: Consider what happens to object stability with height changes.

Challenge Problems

Push your limits with challenges.

Question 1

An iceberg, initially submerged at 80% of its volume, begins to melt underwater. Determine the new submerged volume percentage when its buoyancy changes and causes a potential toppling.

💡 Hint: Consider the change in submerged weight in relation to the total iceberg weight.

Question 2

A cylindrical tank filled with water accelerates horizontally at 5 m/s². Calculate the angle at which the water surface will tilt, using given parameters for density and gravity.

💡 Hint: Recall the relationship between fluid dynamics and pressure gradient in acceleration.
