Category 2: $100 When a negative charge contacts a neutral object it will get what charge? negative

As the distance between two charges increases the force between them…. Category 2: $200 As the distance between two charges increases the force between them…. decreases

Category 2: $300 An object that has had a permanent positive charge induced, the charging object had what charge? Negative

What is an induced charge separation? Category 2: $400 What is an induced charge separation? Separation of charges in a neutral object in relation to an electric field without contact

Category 2: $500 When inducing a charge permanently with a negative object the resulting charge will be ? Positive

What are the two main components of a voltaic cell Category 3: $100 What are the two main components of a voltaic cell Electrode Electrolyte

Difference between a dry and wet cell Category 3: $200 Difference between a dry and wet cell Liquid vs. paste

Explain the function of an electrolyte in a cell Category 3: $300 Explain the function of an electrolyte in a cell Allows ions to flow between electrodes, interacts with electrodes releasing electrons and ions.

Category 3: $400 When does a battery die? When no more chemical reactions can take place (the electrode is used up)

Category 3: $500 Describe how a solar cell works and why it is better for the environment Photons hit silicon atoms releasing e-. Secondary cell, less waste, no fuel
