What is the wavelength of a wave that has a speed of 160 m/s and a period of 3.7 ms? (no downloadable files please, my computer doesn't take them)

What type of light does this light bulb produce most (i. e. at what wavelength does the spectrum have maximum intensity)?

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.

Often called simply "velocity," this is the velocity of an object at a particular moment in time.
