Y9 Buoyancy question short answer x 10

Which ancient Greek scientist discovered the principle of buoyancy while bathing?

(a)  

What do we call the weight an object seems to have when it is partly or fully submerged in water?

(a)  

What word describes the upward force that water exerts on an object placed in it, making the object seem lighter?

(a)  

Which physical quantity of an object determines the size of the buoyant force it experiences in a fluid?

(a)  

What word describes the water that is pushed aside when an object is submerged?

(a)  

If an object’s weight is greater than the buoyant force it experiences, causing it to sink, what type of buoyancy is this?

(a)  

An object experiences a buoyant force of 10 N and has an apparent weight of 17 N in water. What is its actual weight? Enter a numerical value only (do not include units).

(a)  

An object with an actual weight of 8 N and a volume of 100 cm³ is fully submerged in pure water. What is its apparent weight? Hint: 1 cm³ of water has a weight of 0.01 N. Enter a numerical value only (do not include units).

(a)  

An object has an actual weight of 12 N and an apparent weight of 4 N when fully submerged in water. How many cm³ of water did it displace? Hint: 1 cm³ of water weighs 0.01 N. Enter a numerical value only (do not include units).

(a)  

An object with an actual weight of 5 N floats on the surface of water. What is its apparent weight? Enter a numerical value only (do not include units).
