Sam is conducting an experiment in a closed room. he places two sound-generating instruments, a and b, in different places in the room. both instruments generate sound waves of the same amplitude and at the same time. sam is holding a recording device that records a louder sound from instrument a than from instrument b. what could have caused this mismatch in loudness?

instrument a is placed closer to sam than instrument b.
instrument b is placed closer to sam than instrument a.
the sound wave generated by instrument a has a higher pitch.
the sound wave generated by instrument b has a higher pitch.
the sound wave generated by instrument b has a higher wavelength.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

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.
