A55.0-g piece of copper wire is heated, and the temperature of the wire changes from 19.0°c to 86.0°c. the amount of heat absorbed is 343 cal. what is the specific heat of copper? show your work.

Which describe reflection? check all that apply. light bounces off a boundary.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
