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

Which fators influence ocean currents

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
