Aray of light traveling in air strikes the surface of water at an angle of incidence of 35 degrees. calculate the angle of refraction of the light in water. index of refraction of water is 1.33, while that for air is 1.00.

remember to identify all of your data, write the equation, and show your work.

At an oceanside nuclear power plant, seawater is used as part of the cooling system. this raises the temperature of the water that is discharged back into the ocean. the amount that the water temperature is raised has a uniform distribution over the interval from 10° to 25° c. what is the standard deviation of the temperature increase?

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?
