Is there a critical angle for a light ray coming from a medium with an index of refraction 1.2 and incident on a medium that has index of refraction 1.4? If so, what is the critical angle that allows total internal reflection in the first medium?

Light that has been traveling in a medium with a refractive index n2 is incident on the boundary surface of another medium of refractive index n1. Which of the following must be satisfied for total internal reflection to take place?

Why Refraction takes place 

calculate the osmotic pressure at 25C across a semipermeable membrane separating seawater (1.14 M total particles) from a .47 M solution of aqueous NaCl.

Pchem. Please show work . this is one whole problem

1) An aqueous solution of osmotic pressure 5 bar is separated by a semipermeable membrane from an aqueous solution of osmotic pressure 2 bar. Which way will the solvent flow? How Large a pressure must be applied to prevent this solvent flow?

When a nonvolatile solute is added to a volatile solvent, the solution vapor pressure __________, the boiling point __________, the freezing point __________, and the osmotic pressure across a semipermeable membrane __________.

Your GIS team has provided the following elevation raster to your engineering team. As apart of your project planning activities, you were asked to:
Delineate flow direction and flow accumulation for the given elevation raster
Delineate the watershed area based on the flow direction raster.
Estimate the drainage area for the watershed draining to the project outlet. Your raster pixel resolution is 90 meters
Delineate the stream network based on the flow accumulation raster considering a threshold of 40500m2

What is the company Mèrieux nutrisciences in Canada? What does this company do?

Got this question during an interview - Without putting a camera inside the fridge. How would you check to see if the light turns off when you close the door.

I found this one answer on the internet -put a thermometer on the bulb and leave the door shut for 10 minutes. Then open the door and check the thermometer immediately. If it is cold, then you know the bulb was off when the door was closed.

Are there any other answers or the one listed above is the only answer.

Didn't know what category to choose so I selected science.
