The specific heat of liquid mercury is 140 J/kgC. When 1 kg of solid mercury at its melting point of -39C is placed in a 0.5 kg aluminum calorimeter filled with 1.2 kg of water of temperature 20C, the mercury melts and the final temperature of the combination is 16.5 C. What is latent heat of mercury

Experiment scenario 2: a biology student wants to conduct a study of how the amount of food affects the weight gain for mice. i have set up four cages with a mouse in each cage. fill in the boxes that would allow the biology student to complete the study correctly

Will you chech and finish these for me, because i am stumped with them.

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
