F5 Chapter 2.5 Archimedes' Principle

Diagram below shows a swan with mass of 5500g on the surface of water. The weight of water displaced by the swan is

• Equal to buoyant force

• More than the buoyant force

• Less than the buoyant force

• volume of the water displaced

2. Figure below show a man on a float in a swimming pool. Which of the following is true?

• A. Volume of the water displaced>volume of the man + volume of the float
• B. Volume of the water displaced=volume of the man + volume of the float
• C. Weight of the water displaced>weight of the man + weight of the float
• D. Weight of the water displaced= weight of the man + weight of the float

3. Diagram below show icebergs floating on the surface of the water. Which of the following is incorrect?

• A. Weight of the iceberg = weight of the sea water displaced
• B. Weight of sea water displaced> Buoyant force acting on iceberg

• C. Volume of the iceberg= volume of sea water displaced
• D. Volume of the iceberg>volume of the sea water displaced

4. Which of the following is not the application of Archimedes' principle?

• A. Hydrometer
• B. Hot air balloon
• C. Submarine
• D. Aeroplane

5. What will happens to the readings when the load if taken out of water?

• A. Compression balance: decreases ; Spring balance increases
• B. Compression balance: decreases ; Spring balance decrease

Diagram shows a plimsoll line. What is the function of the plimsoll line?

• To indicate the maximum weight of the cargo loaded on the ship.

• To indicate the maximum depth of immersion of the ship that decreases when the salinity of water increases.

• To indicate the capability of the ship to break water and sail on the sea.

• To indicate the maximum depth of immersion of the ship that increases when the density of water increases

8. A hot air balloon accelerating upward because

• A. Weight of the hot air balloon equal to the weight of air displaced
• B. Weight of the hot air balloon is greater than buoyant force
• C. Weight of the hot air balloon is lower than the weight of the air displaced
• D. Weight of the hot air balloon is greater than weight of the air displaced
