Assume that the iron block is 175 g and that the beaker contains 75 m hot water, or 75 gince the density of water
is 1.00 if you heat the metal directly on the burner to
about 275°C and then place it in the room temperature (
25° C) water, the temperature of the combined water and
iron equilibrates at 75º C Note that the specific heat of
water is 4.182, J/g•C
Using these values, what is the specific heat of iron in
units of J/g•C? Please answer to the nearest 0.001
J
9 °C

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)
