The iceberg requires 7.4 x 1020 Joules of energy to melt it completely. It absorbs energy from the Sun at a constant average rate of 88 Watts/m2. The total surface area of iceberg exposed to the sunlight is 12 billion (1.2 x 1010) square meters.  How long will it take for sunlight to melt the entire iceberg in years
1.0 kg block of ice to melt in the kitchen. The temperature in the kitchen is 31 °C. The ice starts out at 0 °C and takes an hour to melt and reach the same temperature as the surrounding room (31 °C). How much heat does the 1.0 kg of ice/water absorb from the room as it melts and heats up to 31 °C in Joules absorbed? Latent heat of fusion for water/ice is 334,000 J/kg Specific heat of water is 4186 J/kg°C
5.84 If the coefficient of static friction between a table and a uni- form, massive rope is μ, what fraction of the rope can hang over the edge of the table without the rope sliding? 5.97 Block A, with weight Figure P5.97 3w, slides down an inclined plane S of slope angle 36.9° at a constant speed while plank B, with weight w, rests on top of A. The plank is attached by a cord to the wall (Fig. P5.97). (a) Draw a diagram of all the forces acting on block A. (b) If the coefficient of kinetic friction is the same between A and B and between S and A, determine its value. 36.9° 1
