of copper Very long answer questions. Metal Specific seat capacity 910 J/kg °C А A B 380 J/kg °C 470 J/kg °C С The specific heat capacity of substances 'C' is 470 J/kg°C. What does it mean? bifequal heat is given to equal masses of the three substances. Which one will have the lowest temperature? Why? which substance will gain more temperature while heating equal mass of all three bstances with equal amount of heat? nich substances will penetrate to the greatest depth of each with equal mass are put on a wax-slab after heating to 100 °C each? Why? Specitic heat capacities of three different substances are given in the table below. Answer the following questions on the basis of the table.

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
