A closed box is filled with dry ice at a temperature of -87.2 °C, while the outside temperature is 22.7 °C. The box is cubical, measuring 0.268 m on a side, and the thickness of the walls is 4.04 x 102 m. In one day, 3.12 x 106 J of heat is conducted through the six walls. Find the thermal conductivity of the material from which the box is made.

WEEK 4 LESSON 2 Worksheet The apparatus shown below may be used to investigate how the volume of a fixed mass of gas at constant temperature varies when the pressure is changed. Air is trapped in a uniform glass tube which has a scale behind it calibrated in cm³. As the pressure in the oil chamber is increased using the pump, oil is forced into the glass tube, decreasing the volume of the air. The pressure, in kPa, is indicated by a gauge fitted to the oil chamber.

PRACTICE IT Use the worked example above to help you solve this problem. Aluminized mylar film is a highly reflective, lightweight material that could be used to make sails for spacecraft driven by the light of the sun. Suppose a sail with area 1.07 km2 is orbiting the Sun at a distance of 1.39 x 1011 m. The sail has a mass of 5.21 x 10° kg and is tethered to a payload of mass 2.09 x 104 kg. (a) If the intensity of the sunlight is 1.34 x 103 W/m? and the sail is oriented perpendicular to the incident light, what radial force is exerted on the sail? (b) About how long would it take to change the radial speed of the sail by 1.00 km/s? Assume that the sail is perfectly reflecting. (c) Suppose the light were supplied by a large , powerful laser beam instead of the Sun. (Such systems have been proposed.) Calculate the peak electric and magnetic fields of the laser light.
