The sled experiences friction against the ground
Answer:
a) moves down
b) moves down
c) level remains same
Explanation:
Given that the anchor is initially on the floating boat.
a)
In this condition initially the the volume of water 
displaced is to balance its weight.
Now,
We've, the density of steel 
and the density of water 
When the anchor is dropped into water:
The volume of water displaced be 
which will be equal to the volume of anchor since it is immersed into it.
...................(1)
So the level of water falls when the anchor is dropped into water.
b)
Now, when the anchor is thrown on the ground the water has now less weight to balance so the water level falls down.
c)
When the cork on the from the boat is dropped into the water and it still floats then it must displace same amount of water, hence there should be no change in the water level.
Explanation:
Hey, there!
Answer: It sinks more.
We know that the water of sea is salty in nature which increases the density of water in sea and donot let's ship sink but in condition of river water it doesn't have any effects of salty water as it doesn't contain salty water due to which it's density is no more than the densityof ship which let's it sink more than sea water.
