(this is somehow part of my science unit, dont ask why) the height of a coffee mug would be about: 50 mm 20 cm 8 m 0.1 km

 Height of coffee mug = 5 cm

Explanation:

  Changing all the data given in to unit cm

              50 mm = 5 cm

              20 cm  = 20 cm

              8 m    = 800 cm

              0.1 km = 100 m = 10000 cm

Since we need to find the height of coffee mug, it's height will not be more than 10 cm.

  So 5 cm is the correct choice.

this means that the temperature of both substances will be equal

did yall get answers for this yet
