Answer:
0.5 mph in the opposite direction
Explanation:
= Mass of Cadillac = 1000 kg
= Velocity of Cadillac = 1 mph
= Mass of Volkswagen = 2000 kg
= Velocity of Volkswagen
In order to know the speed the system must have the momentum exchange
As the linear momentum of the system is conserved
The speed of the impact is given by 0.5 mph in the opposite direction
The distance from the horizontal top surface of the cube to the water level is "6.282 cm".
<h3>What is Archimedes' principle?</h3>According to Archimedes' principle, the weight of the fluid that the body displaces is equal to the upward buoyant force that is applied to a body submerged in a fluid, whether fully or partially. The Archimedes' principle is a fundamental physical law in fluid mechanics. It was created by Syracuse's Archimedes.
According to Archimedes' principle, a body submerged in a fluid experiences an upward force proportional to the weight of the fluid that has been displaced. One of the prerequisites for equilibrium is this. We believe that the buoyancy force, also known as the centre of buoyancy, is situated in the middle of the submerged hull.
From Archimedes' principle, we get
=11.72cm
So,
The distance from horizontal top to the water level will be:
=18-11.72
=6.282cm

Answer:
Pressure difference between Top and Bottom of the cylinder is given as
Explanation:
As we know that the force due to pressure is balanced by the weight of the cylinder
So we will have
so we have
so we have
so we have
