- An aluminum wing on a passenger jet is 35 m long when its temperature is 22°C. At what temperature would the wing be 6 cm (0.06 m) shorter?Week 4 #19 A copper bar of thermal conductivity 401 W/(m·K) has one end at 114°C and the other end at 24.0°C. The length of the bar is 0.110 m, and the cross-sectional area is 1.00 × 10−6 m2. If two such bars were placed in parallel (side by side) with the ends in the same temperature baths, what would the rate of heat conduction ? be? ______WA styrofoam cooler (k = 0.030 W/(m-°C) has outside dimensions of 0.170 m x 0.250 m x 0.260 m, and an average thickness of 2.0 cm. How long will it take for 1.10 kg of ice at -5.0°C to melt (to water at 0°C) in the cooler if the outside temperature is 34.0°C? Assume that ice temperature increases linearly from -5.0°C to 0°C. Neglect any temperature change of the air in the cooler. Data: Specific heat of ice is 2050 J/(kg-K). Laten heat of fusion of water is 3.34×105 J/kg.
- Because water is a much more efficient thermal conductor than air, marine mammals often have thick layers of blubber (under-skin fat, with a thermal conductivity of 0.250 W/(m °C)) and a small surface-to-volume ratio to minimize the loss of energy by heat to the surrounding water. The beluga whale, Delphinapterus leucas, is a species of whale native to the Arctic and sub-Arctic regions. The core body temperature of this whale is usually 37.0°C, and its basal metabolic rate (BMR) is 7.30 x 104 kJ/day. The beluga often finds itself near the Arctic ice sheet, where the water temperature is very close to 0°C. (a) Modeling the body of the whale as a cylinder of length h = 4.10 m and diameter d = 1.20 m,estimate the average thickness (in cm) of the beluga's blubber required to keep the core temperature of the whale fixed at 37.0°C. (For simplicity, treat the blubber layer on the lateral cylindrical surface as a rectangular slab with a constant area. Take the front and rear surfaces of the…Suppose you have two meter sticks, one made of steel and one made of invar (an alloy of iron and nickel), which are the same length (1.00 m) at 0°C. The coefficients of volume expansion for steel and invar are 3.6 × 10-5 /°C and 2.7 × 10-6 /°C respectively. apparently, you need to use the volume expansion formula below & have B=3a. have no idea how to turn the length into a volume for this problem. have no idea what value alpha is...At 68°F, an aluminum ring has an inner diameter of 5.000 cm, and a brass rod has a diameter of 5.050 cm. Keeping the brass rod at 68°F, which of the following temperatures of the ring will allow the ring to just slip over the rod? (αAl = 2.4×10-5 / K; αCu = 1.9×10-5 / K) 111°C 236°C 384°C 437°C
- Thank u! A steel rule is calibrated for measuring lengths at 20.00°C. The rule is used to measure the length of a Vycor glass brick: when both are at 20.00°C, the brick is found to be 30.90 cm long. If the rule and the brick are both at 85.00°C, what would be the length of the brick as measured by the rule? Coefficient of linear expansion a for steel is 12.0 x10^-6 K-1 and for glass (Vycor) is 0.750 x 10^-6 K^-1.An aluminum wing on a passenger jet is 31 mlong when its temperature is 23°C. At what temperature would the wing be 6 cm (0.06 m) shorter?
