Why a perspex block sinks in fresh water but will float in very salty water?
salt water is denser than fresh water so it will produce more upthrust due to Archimedes principle
Why is it that ship floats deeper in fresh water than in the sea water?
sea water is denser.
Why do needle sinks in water but ship floats?
Whether something sinks when it's placed on water is determined by the amount (weight) of water that it displaces. The needle, being small in size and relatively high in mass (relative to its size), displaces very little water when it is placed on the surface. The weight of the needle will be more than the weight of the water that it displaces and the needle will sink. The ship, though many times heavier than the needle, will displace alot more water than the needle. The ship will float if the weight of the displaced water is more than the weight of the ship.
Why a ship sinks more in fresh water than sea water?
A ship will sink more easily, when in fresh water instead of sea water, as the fresh water is less dense, due to a lack of salt in it. The density of any object affects how well it's able to float.
Will a ball float higher in salt or fresh water?
Salt water is more buoyant than fresh water is, because salt water is slightly more dense. -- Anything that floats in salt water will float higher than it does in fresh water. -- Anything that sinks in salt water will sink slower than it does in fresh water. -- Anything that just barely floats in salt water may possibly sink in fresh water.
Why does a ship entering from fresh water to sea water sinks more?
You have it backwards. A ship floats higher in seawater than freshwater. This is because the dissolved salt makes seawater denser. due to the lack of salt content in fresh water. the salinity of ocean water makes it more dense, allowing the boat to sit higher in the water.
A steel needle sinks in h20 but a steel ship floats?
The needle is solid, it's density higher than water's. The ship is hollow, its overall density lower than water's.

Why is it that ship floats deeper in fresh water than in the sea water?
sea water is denser.
There are two reasons why tropical freshwater produces less upthrust than water in winter in the north atlantic but what are they?
In tropical seas the water is warmer so it is less dense than in colder areas. The ship sinks lower in water, as cargo is loaded, to displace a greater weight of water. Fresh water also produces less upthrust than sea water.
Will the ship sink further into the seawater than if it was in fresh water?
The ship will sink slightly. Salt water is denser there for heavy objects will float more in it. When the ship goes back to fresh water the density decreases and the ship lowers again.

Why ships floating in the sea?
ship float in the sea because water has less density than any substance ship has much weight and thatswhy it sinks

Why aft of the ship safer than forward?
the ship's aft is safer than the forward bcos if the ship sinks or capsizes in most cases the stem will go into the water first .... so there is a greater possibility of escaping if a person is in the aft of the ship...
Why a coin sinks while a ship floats?
Ultraoversimplifying it, the coin is solid metal all the way through and weighs more than its volume of water, the ship has a large space filled with air inside it resulting in the weight of the ship and cargo being less than the weight of the volume of water it occupies.This is called buoyancy: the coin has negative buoyancy and sinks, the ship has positive buoyancy and floats.
