QUESTION 6An electric stove burner of diameter 20 cm is at temperature of 250 °C. If o= 5.67 x 10-8 W/m2 K4, at what rate is the burner radiating energy? Assume the emissivity & = 0.4.QUESTION 7Ten grams of ice at -20°C is to be changed to steam at 130°C. The specific heat of both ice and steam is 0.5 cal/g °C. The specific heat of water is 1.00 cal/g x K. The heat of fusion is 80 cal/gand the heat of vaporization is 540 cal/g. How many calories does the entire process require?QUESTION 8What mass of steam (in grams) at 100°C must be mixed with 150 g of ice at its melting point, in a thermally insualted container, to produce liquid water at 50°C?QUESTION 9The coefficient of linear expansion of steel is 11 x 10-6 per Cº. A steel ball has a volume of exactly 100 cm³ at 0°C. What is its volume (in cubic centimeter) when heated to 100°C? Round youranswers to 2 decimal places.QUESTION 10An aluminum-alloy rod has a length of 10.000 cm at 20.000C and a length of 10.015 cm at the boiling point of water. What is the coefficient of linear expansion of the rod? Answer in decimal form. QUESTION 1A hydraulic press has one piston of diameter 2.0 cm and the other piston of diameter 8.0 cm. What force must be applied to the smaller piston to obtain a force of 1600 N at the larger pistonQUESTION 2Water flows from a 6.0-cm diameter pipe into an 8.0-cm diameter pipe. The speed in the 6.0-cm pipe is 5.0 m/s. The speed (in m/s) in the 8-cm pipe is:QUESTION 3A shearing force of 50 N is applied to an aluminum rod with a length of 10 m, a cross-sectional area of 1.0 x 10-5 m, and shear modulus of 2.5 × 1010 N/m². As a result the rod is sheared through adistance (in mm) of.QUESTION 4A force of 5000 N is applied outwardly to each end of a 5.0-m long rod with a radius of 34.0 mm and a Young's modulus of 125 x 108 N/m². The elongation of the rod in millimeters is:QUESTION 5One end of a cylindrical pipe has a radius of 1.5 cm. Water (density = 1.0 × 103 kg/m³) streams steadily out at 7.0 m/s. The volume flow rate is:
