Electric Charge Charges that are the same repel each other. Charges that are different attract each other. This rule is the same rule for interactions between magnetic poles. Protons repel protons and attract electrons because they have different types of electric charges. Protons have a +ve charge and electrons have a -ve charge. This interaction…
1. Renewable energy source: a source of energy; such as water, which can be replaced or restocked in a human lifetime. 2. Non-renewable energy source: a source of energy; such as fossil fuels and uranium, which cannot be replaced or restocked in a human lifetime. 3. Negative charges: the type of electrical charges that can…
Humans are very reliant upon electricity. Think back to the blackout of August 2003 and recall how whole cities were shut down. Since we rely on electricity so much, it’s important to produce as much of it as possible and conserve it whenever we can. All energy sources are either renewable or nonrenewable. A renewable…
In the mid-1800’s there were 64 known elements (today there are over 116 elements). Scientists kept having difficulties organizing the information about the 64 elements. They kept trying to organize them, but found no pattern between them. Many chemicals have very similar colours, lustre, and conductivity of electricity and heat. Scientists were able to classify…
