A loaded cargo ship sails from sea water to river water. State and explain your observation
Answer:
The observation is as follows:
The cargo ship dips into water as it advances from seawater to river water.
Explanation: The density of sea water is more than that of river water. Consequently, as per the law of floatation, in order to balance the weight of the ship, more volume of water is required for the
river water having lower density to displace it.

"hello everyone welcome to lado learning
i am good preet your science tutor
today's question is
a loaded cargo ship sails from
sea water to the river water state and
explain
your observation so here a situation is
given
that a loaded cargo ship
it sails from sea water to river water
so what do you
observe so the observation
here is
the cargo ship
will dips into
water as it
sails from
sea water to river water
okay the observation is that the ship
will
dip into the water
now what will be the explanation
for this observation
as the density of
sea water
is more
than the river water
consequently from the law of
flotation
to balance the weight of shape
the weight of shape
more volume
of water is required
and river water
have
lower density
lower density
to displace
the ship that is why
when the ship the loaded cargo ship
sails from sea water to river water
it get dips into the water
