The accepted value for the speed of light in a vacuum is 2.99792458 x 10 ms. three groups of students made independent measurements of the speed of light ca (2.9870.002) x 10 ms-1 cg = (2.997 ± 0.005) × 108 ms-1 cc = (2.8999 ± 0.0005) × 108 m s-1 state which of the measurements is the most (i) accurate (ii) precise

The speed of light can be used to measure the

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.
