Three liquids are at temperatures of 10 ◦C,
25◦C, and 32◦C, respectively. Equal masses of
the first two liquids are mixed, and the equilibrium temperature is 12◦C. Equal masses of
the second and third are then mixed, and the
equilibrium temperature is 28◦C.
Find the equilibrium temperature when
equal masses of the first and third are mixed.
Answer in units of ◦C.

Mutt and jeff are running along a path each pushing a cart loaded with rocks. if mutt's wagon has a mass two times greater than jeff's and they want to stay together, arriving at their destination at the same time, what must happen? a) jeff should slow down so mutt can catch up. b) mutt must use half as much force to push his cart. c) mutt must use twice as much force to push his cart. d) mutt and jeff will use the same force, but mutt will take bigger steps.

The softest and hardest minerals are: softest hardest
