We would like to measure the density (r) of an ideal gas. we know the ideal gas law provides � = $ %& , where p represents pressure, r is a constant equal to 287.058 j/kg-k and t represents temperature. we use a pressure transducer to take 15 measurements, all under the same conditions. the sample mean and standard deviation obtained from these 15 pressure measurements are 120,300 pa and 6,600 pa respectively

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?

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.
