Q30. When working near some large air cored inductors you misplace a socket and as you cannot find it you
proceed to energise the system. However, you find that something does not operate as expected. Upon
investigation you find that the socket had fallen into a coil. Select the best explanation for what happened.
The socket became permanently magnetised
The socket changed the inductance of the coil
The socket introduced an air gap into the original core
The socket caused a change in the magnetic circuit shorting out the coil

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)

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)
