1. compare and contrast charging by contact, charging by
friction, and charging by induction.
2. the leaves of a metal leaf electroscope are slightly separated,
indicating that it is charged. when you bring a positively charged
rod near the sphere, the leaves spread farther apart. what charge
is on the electroscope? draw diagrams to explain your answer.
3. see figure 10.13. how does the strength of an object's electric

sample ressponse: When two objects with unlike charges are brought near each other, their electric field lines combine, showing that the objects attract each other.

Explanation: hope this helped :)

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
