A student attaches a block to a horizontal spring so that the block-spring system will oscillate if the block-spring system is released from rest at a horizontal position that is not the system’s equilibrium position. The oscillatory motion of the system is described by the graph of the block’s acceleration as a function of time. An identical experiment is conducted except that a new spring is used that has a spring constant that is twice the value of that of the original spring. Which two of the following predictions are correct about the system when it undergoes simple harmonic motion? Select two answers.
The amplitude of oscillation will be increased by a factor of 2.
The maximum acceleration of the system will be 10 m/s2.
The period of oscillation for the system will be nearly 5.7 s.
The maximum spring potential energy of the system will be increased by a factor of 4.

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.
