The fraction of Oil will be 0.8and block will be 0.95
What is density?
Density is the ratio of Mass of a compound upon Volume of that compound. It's SI unit can be g/cm³, kg/m³.
As we know the Density of water is 997Kg/m³≈1000Kg /m³.
1) Fraction of Oil is
800/1000=0.8
2) Fraction of Block is
950/1000= 0.95.

Answer:
The object with a higher mass has three times the kinetic energy of the less massive object.
We know that K.E.= 1/2 mv²
mass of first object = 1kg
speed = v
So K.E. = 1/2mv²
= 1/2 × (1) × v²
=
Now the mass of second body = 3kg
speed = v
So K.E. = 1(3)v²/2
=
now
K.E of first / KE of 2nd
Answer:
Answer is 0
Explanation:
Given the information
First mass = m
Second mass = 3m
Initial velocity = v
Final velocity = v/3
The collision occuring here is inelastic and in inelastic collisions the kinetic energy is not conserved however the momentum is conserved.
According to conservation of momentum initial momentum is equal to final velocity.
Conservation of momentum is =
m1v1 + m2v2 = (m1 +m2)vf
Rearranging the equation to get final velocity we have =>
mv - 3mv/3 = 4mvf
vf = 0
