Answer
a) Draw an upward force from the bottom to indicate upthrust
b) Upthrust is an upward force acting on an object floating on a liquid... hence there is an upward force acting on the iceberg which causes it to float.
c) Unfortunately I don't know the answer.
Displacement is how far something is from its starting position
for example if X moved 10 feet, turned around and moved 30 feet, its distance would be 40, but the displacement would be 20,
and if Y Moved 2 feet, and turned around and moved 22 feet, its distance would be 24, but its displacement would also be 20
