Answer:
The maximum potential energy of the net, compared to its unstretched potential energy, is:
Explanation:
From the question we are told that
The weight of the man is
The distance of the window to the net is
The distance stretched by net is
Generally from the of conservation energy , the total energy is conserved
This implies that
Where is the initial potential energy of the , man which is mathematically evaluated as
Substituting values
And is the unstretched potential energy of the net
And is the final potential energy of the man which is mathematically evaluated as
Substituting values
The negative show that the direction of the man is against the direction of gravitational pull
And is the maximum potential energy of the net when stretched
So the above equation becomes
So
The density of hematite ore is <u>4.78 g/cm³</u>.
Let the mass of the ore be m₁ , the volume of the flask <em>V</em>, total mass of water and ore M, mass of water be m₂, density of ore ρ₁ and the density of water be ρ₂.
Density of a substance is defined as the mass per unit volume.
The mass of water in the flask is given by,
Calculate the volume V₂ of the water in the flask.
Calculate the volume V₁occupied by the ore in the flask.
1 ml is equivalent to 1 cm³.
Calculate the density of the ore.
The density of the hematite ore is found to be 4.78 g/.cm³
