A peanut can has the usual “can shape” of a circular cylinder. Its sides are made of cardboard, its bottom is made of thick plastic-coated aluminum foil, and its top lid is made of clear plastic. It must have a volume of 480 cubic centimeters. The cardboard material used for the sides costs 0.1 cents per square centimeter, the foil material used for the bottom costs 0.3 cents per square centimeter, and the plastic material used for the top lid costs 0.5 cents per square centimeter. What dimensions should the can have in order to minimize the cost of the materials from which it is made?

A Gaussian surface in the shape of a right circular cylinder with end caps has a radius of 16.4 cm and a length of 68.1 cm. Through one end there is an inward magnetic flux of 36.6 μWb. At the other end there is a uniform magnetic field of 1.40 mT, normal to the surface and directed outward. What are the (a) magnitude and (b) direction (inward or outward) of the net magnetic flux through the curved surface?

An infinitely long, solid non-conducting rod (cylinder) with circular cross section of radius a has its axis along the z-axis. It has a non-uniform volume charge density given in cylindrical coordinates by ρ(s) = C (s/a)^2 ,where C is a positive constant. In addition, there is a uniform volume charge density −σ on the outer cylindrical shell of radius b, where σ is a positive constant. Region 2 is a vacuum. For parts (a) through (c), use Gauss’ Law and...

A thermos bottle in the shape of a cylinder has an inner radius of 4.0 cm, an outer radius of 4.5 cm, and a lengt of 30cm. The insulating walls have a thermal conductivity equal to 2.0 x 10^-5 cal/(sec-cm celsius). One liter of hot coffee at 90 degrees Celsius is poured into the bottle. If the outside wall remains at 20 degrees Celsius, how long does it take for the coffee to cool to 50 degrees Celsius?

1) Write a simple python function program that can calculate the volumes of following shape: cylinder, circle, cone and sphere. For each of this shape, write a separate function. Let your function take in 2 inputs only. Your program should prompt user to enter these 2 inputs and print out the results of the volumes of the shape separately?

A measuring cylinder made of glass has a volume of 200 mL when measured at 20°C. Mercury, also at 20°C, is added to the measuring cylinder until the mercury level reads 197 mL on the measuring cylinder scale. The mercury and glass are then warmed until the mercury level reads 200 mL on the measuring cylinder scale. Taking the coefficients of volume expansion of glass to be 2.0 × 10-5 K-1 and for mercury to be 18 × 10-5 K-1,...
