A1730-n irregular beam is hanging horizontally by its ends from the ceiling by two vertical wires (a and b), each 1.30 m long and weighing 0.320 n . the center of gravity of this beam is one-third of the way along the beam from the end where wire a is attached. part a if you pluck both strings at the same time at the beam, what is the time delay between the arrival of the two pulses at the ceiling? (neglect the effect of the weight of the wires on the tension in the wires.)

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)

Apair of 10μf capacitors in a high-power laser are charged to 1.7 kv.a. what charge is stored in each capacitor? b. how much energy is stored in each capacitor?
