Question 3 Light Now click the Light tab.
Part A
On the light tab, once again investigate briefly all the phenomena you explored with water and sound above. Describe any similarities in your
results for light. Specifically describe
• wave pattern as seen on the screen
• shape and amplitude of the graph
• effect of frequency on wavelength
• effect of frequency on velocity

The percent efficiency of a machine can never be 100% (or greater), because in the real world some energy is always converted into a. heat b. work c. input force d. output force

Aphysical change is a change in the size, shape,, or stafe of matter true or false

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.
