Ahowler monkey is the loudest land animal and under some circumstances, can be heard up to a distance of 5.0 km. assume the acoustic output of a howler to be uniform in all directions and that the threshold of hearing is 1.0*10^-12 w/m^2. the acoustic power emitted by the howler is closest to a) 3.2 mw b) 0.11 mw c) 11 mw d) 1.1 mw e) .31 mw

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)
