Answer:
the mass of the body is 0.02 kg.
Explanation:
Given;
relative density of the oil, = 0.875
mass of the object in oil, = 0.013 kg
mass of the object in water, = 0.012 kg
let the mass of the object in air =
weight of the oil,
weight of the water,
The relative density of the oil is given as;
Therefore, the mass of the body is 0.02 kg.
Answer:
1863 J
Explanation:
F = Force moving the object
f = Frictional force = 230 N
The forces in the horizontal direction have the force balance
So, the force by which the object is being pushed is
s = The displacement of the object = 8.1 m
Work done is given by
The work done by the mover is 1863 J.
