Figure 1 represents the profile of a transverse wave on a string (t = 0) in the positive X-direction at a speed of 20.0 m/s. a) Determine the wavelength and the frequency of this wave.
b) calculate the maximum speed of the string oscillates between the two amplitudes. name this type of speed
​

Which law represents the thermodynamic statement of the conservation of energy of a system? a. the fourth law b. the first law c. the second law d. the third law

What is the speed of an object at a given moment?

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.
