Concept simulation 13.1 illustrates the concepts pertinent to this problem. a person's body is covered with 1.50 m2 of wool clothing. the thickness of the wool is 1.90 × 10-3 m. the temperature at the outside surface of the wool is 9.13 °c, and the skin temperature is 34.4 °c. how much heat per second does the person lose due to conduction?

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?

Explain what will happen if decomposers were apsent from a forest ecoysystem.

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
