Ahot reservoir with a temperature of 786 k is 0.32 m away from a cold reservoir with a temperature of 332 k. the two reservoirs are insulated from each other except for a rod of brass (k = 109 w/m-k) that has a cross-sectional area of 0.032 m2. the entire system is allowed to reach a steady-state condition. 1) how much energy is transferred by heat between the hot reservoir and the cold reservoir in ten minutes?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
