Awell-greased, essentially frictionless, metal bowl has the shape of a hemisphere of radius 0.150 m. you place a pat of butter of mass 5.00ã10â3kg at the rim of the bowl and let it slide to the bottom of the bowl. what is the speed of the pat of butter when it reaches the bottom of the bowl?

Ineed extreme for task 2. my student number is 571721. many to whoever solves this correctly, im in debt to you.

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.

What are the factors that affect the resistance of a wire?
