Section B (3 marks)​

Answer 1

Answer:

That generally means that Ww = 2/3 Wa. If Wa is a 10-pound rock above the water, it should weigh around 6.6 pounds when submerged underwater. If Wa is a 300-pound boulder, it will weigh about 200 pounds underwater. Looking at it another way, it is the water which supports one-third of the rock's weight.

Answer 2

Answer:

a block of metal weighs 600 Newton in air in water the weight of metal block become less because boyency force or upthrust act on block of metal in upward direction which decreases the weight of body .

that is

If initial weight is 600N

then final weight = 600N - upthrust force exerted by water
