Astudent finds an unlabeled liquid container in his lab. he notices that the container has two liquids. since the two liquids have different density, there is a distinct separation between them. water, which has a density of 1.00g/cm^3, fills the lower portion of the container to a depth of 20.0 cm. the fluid which is floating on top of the water is 30.7 cm deep. if the absolute pressure on the bottom of the container is 104900 pa, what is the density of the unknown fluid? the acceleration due to gravity is g=9.81 m/s^2 and atmospheric pressure is p0=101300 pa.

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?

Scout feels ill one day before school. her mother puts a thermometer in her mouth and the temperature begins to climb to 100°f. what is happening between the cooler thermometer and scout's body? a) scout's body is applying a force to the particles in the thermometer. b) kinetic energy is being transferred from her mouth to the thermometer. c) potential energy is being lost by the thermometer and gained by scout's body. d) the potential energy stored in foods is converted to mechanical energy to raise the mercury in the thermometer.
