Asheet of gold weighing 12.0 g with an initial temperature of 15 °c is placed flat on a 20.0g plate of iron that has been heated to 55°c. what is the final temperature of both pieces of metal? the specific heat of iron is 0.449 j/g°c and the specific heat of gold is 0.129 j/g°c.

What would be the result of an alpha particle coming into a magnetic field? a) the alpha particle will stop moving. b) the alpha particle will reverse its direction. c) the alpha particle will be deflected in a curve path. d) the alpha particle will continue to travel in a straight line.

Which situation will produce the greatest change of momentum

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
