Find the final equilibrium temperature when 10.0 g of milk at 10.0°C is added to 160 g of coffee at
90.0°C. (Assume the specific heats of coffee and milk are the same as water and neglect the heat capacity of the container.) cwater = 4186 J/kg °C

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
