A tank in the shape of an inverted right circular cone has height 4 meters and radius 2 meters. It is filled with 3 meters of hot chocolate. Find the work required to empty the tank by pumping the hot chocolate over the top of the tank. The density of hot chocolate is δ=1020 kg/m3.δ=1020 kg/m3. Your answer must include the correct units.

The required work to empty the the tank is 247401 J.

Explanation:

Given that,

A tank is in the shape of right circular cone.

The radius of the tank= 2 m

The height of the tank = 4 m

The relation between the radius and the height is

Let h be the height of hot of chocolate any time t.

The volume of a cone is

The volume of the chocolate is

The mass of the  chocolate is(M)= Density × Volume

                                                      Kg

                                                      kg

Work done = Force × displacement

                  = Mass × acceleration×displacement

Here acceleration= acceleration due to gravity = 9.8 m/s²

The displacement when the hot chocolate level is h is = (4-h)                  

Work done (dw)

Work done = W

                        =247401 J

The required work to empty the the tank is 247401 J.

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

scientific laws are the result of testing theories and proving them to be facts.
