Notes: When a ship enters a sea from a river ,the ship is
elevated or uplifted due to the density of sea water
and during the buoyant motion of the ship, as it would gain both potential and kinetic energy when rising in the fluid.
When a ship enters sea from a river it?
The correct answer is It
rises a little
. A ship rises a little when enters the sea from a river. Because of salinity, seawater has more density than river water. In the sea, the more buoyant force is exerted upon the ship than in the river.
What happens when a ship moves from saltwater to freshwater?
When the vessel moves from saltwater to fresh water due to
the difference in density the vessel will sink so that summer loadline will submerge below water line
. This additional sinkage will be just enough to achive more underwater volume so that vessel will get exact buoyancy as the vessel floating in sea water.
When a ship coming from sea enters the river will its hull sink more or less?
A ship
sink more
in river water than in sea water because the density of sea water is more than that of river water due to the presence of impurities.
When a ship enters from river to sea it raise upwards Why?
Considering the ship displaces equal volumes of water in sea and river, as density of sea water > density of river water, Buoyant force by sea water> buoyant force by river water. So when a ship enters from river to sea, it gets raised
a little due to greater buoyant force
.
When a ship enters sea water from fresh water it sinks less?
Answer Expert Verified
According to Law of Flotation, to balance the weight of ship, a
greater volume of water is required
to be displaced in the sea of water of lower density[river water]; Hence it sinks more.
What force makes a ship float?
The answer to why ships can float comes from the famous principle of Archimedes which says that the
net upward force
on an object immersed in water is equal to the weight of the water displaced by the object.
What will happen to the water level on a cargo ship as it goes from the ocean salt water up into a river port fresh water )? Explain?
Because saltwater is denser than freshwater, regardless of the water depth,
ships will float lower in freshwater than in saltwater
. If they are not loaded properly and encounter less dense water, they may float too low.
Why ship floats on sea and sinks in river?
When a ship displace water volume of more or equal weight in comparison to its own weight; the ship will float and this concept is called principle of flotation. … But
when metacenter lies below the center of gravity
; the weight and buoyant force leads the ship to topple ( overturn ) causing the ship to sink.
Why is that no one sinks in the Dead Sea?
The Dead Sea is landlocked and in the lowest valley on earth. All the minerals of the surrounding countryside get washed into one pool, which in turn gets baked by the sun. This concentrates the salts so much so that
the Dead Sea becomes times as salty as the ocean
, which defines why people don't drown in the dead sea.
When a ship leaves a river and enters the sea Mcq?
Notes: When a ship enters a sea from a river ,the ship is
elevated or uplifted due to the density of sea water
and during the buoyant motion of the ship, as it would gain both potential and kinetic energy when rising in the fluid.
Why did ship float on water?
The air that is inside a ship is much less dense than water
. That's what keeps it floating! … As a ship is set in water, it pushes down and displaces an amount of water equal to its weight.
When a river enters the sea A delta is formed?
A river delta is a landform created
by deposition of sediment that is carried by a river as the flow leaves its mouth and enters
slower-moving or stagnant water. This occurs where a river enters an ocean, sea, estuary, lake, reservoir, or (more rarely) another river that cannot carry away the supplied sediment.
Does a ship that enters a freshwater?
Does a ship that enters a freshwater lake from the ocean sink more or rise more? Justify your answer. Answer:
The ship sinks more
. … So the ship that enters a freshwater lake from the ocean sinks more.
Does a ship that enters a freshwater lake from the ocean sink more or rise move?
Since fresh water doesn't have all the salts dissolved in it, a volume of fresh water weighs less than the same volume of seawater. Therefore the
ship has to displace more fresh water to equal her weight
, and the ship sinks in order to do that.
What does salt water do to an egg?
Saltwater is denser than fresh water because of its salt content. The egg will sink in the fresh water because it has greater density than the water. The
egg will float in
the salt water because when salt is added to water its density becomes greater than that of the egg. That makes the egg float.
