Anuclear fuel element of thickness 2l is covered with a steel cladding of thickness b. heat generated within the nuclear fuel at a rate q . is removed by a fluid at t, which adjoins one surface and is characterized by a convection coefficient h. the other surface is well insulated, and the fuel and steel have thermal conductivities of kƒ and ks, respectively. (a) obtain an equation for the temperature distribution t(x) in the nuclear fuel. express your results in terms of q . , kƒ, l, b, ks, h, and t. (b) sketch the temperature distribution t(x) for the entire system

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? question 2 options: the balloons rise at the same rate. both balloons are the same size. the ballons both rise. the cold ballon is larger than the warm balloon. the cold balloon expands and rises. the warm balloon shrinks and sinks. the warm balloon expands and rises. the cold balloon shrinks and sinks.
