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.
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.
