Out in the woods filming a documentary about timber rattlesnakes, your video camera runs out of batteries. The camera draws 0.25 A of current, and has an overall resistance of 72 ohms. What voltage supply does this camera need - well your last 6 pack of 9V batteries do the job?

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.

How are the crust and the inner core alike? a) they are both solid. b) they both have the same temperature. c) they are both under the same pressure. d) they are both very close to the center of the earth.

Convection currents are caused by differences in what two things?
