The table below shows data from an experiment in which a student measured the temperature of water in various states. image

Which of the following would be a valid conclusion for this experiment?

A.
The particles in the ice water have less energy than the particles in the ice.

B.
The particles in the ice water have more energy than the particles in the boiling water.

C.
The particles in the boiling water have more energy than the particles in the ice water.

D.
The particles in the ice have more energy than the particles in the water.

Two red blood cells each have a mass of 9.0 multiply.gif 10-14 kg and carry a negative charge spread uniformly over their surfaces. the repulsion arising from the excess charge prevents the cells from clumping together. one cell carries −2.50 pc of charge and the other −3.10 pc, and each cell can be modeled as a sphere 7.5 μm in diameter. (a) what speed would they need when very far away from each other to get close enough to just touch? assume that there is no viscous drag from any of the surrounding liquid. answer is: 321 m/s how do i find this (b) what is the maximum acceleration of the cells in part (a)? answer is: 1.38e+10 m/s2 how did they find this answer

How do we measure or think of speed in the united states?

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.
