Stone sinks due to its density while ship floats due to its shape and displacement.

• Stone has a higher density than water, causing it to sink.

• Ships are designed to displace water, creating an upward force that keeps them afloat.

• The shape of the ship's hull also helps to distribute its weight and create buoyancy.

• Ships can also adjust their ballast to control their buoyancy.

• Archimedes' principle explains why objects float or sink in water.

• The weight of the water displaced by the...read more

Diesel engine works by compressing air in the cylinder, injecting fuel, and igniting the mixture.

• Air is compressed in the cylinder by the piston

• Fuel is injected into the cylinder at high pressure

• The heat generated by the compressed air ignites the fuel

• The expanding gases push the piston down, creating power

• Diesel engines are more efficient than gasoline engines
