Calculate the electric force between two point charges of 4.00 µC and 3.00 µC when they are 2.00 cm apart. 2. Two points of equal charge produce an electric force on each other of 3.40x10 -2 N when placed 0.100 m apart. What is the charge on each point? 3. How far apart are two point charges of 2.0x10-6 C and 4.0x10-6 C if they produce an electric force of 0.56

Why is advertising an ethical problem? If it is‚ it is because it is often intrusive‚ deceptive‚ or manipulative -- or‚ at least‚ this is what people say about it. Another problem is the money and resources devoted to advertising; billions are spent each year (around $500 billion in fact) that‚ perhaps‚ could go to education‚ health care‚ research‚ reforestation‚ or other worthy causes. We’ll come back to this‚ but first we look at the problem of deception. Could argue that it distorts

The Solution to the Earths’ Energy Conservation Problem Gas prices have hit $6.00 a gallon! That is a scary thought‚ but reality is if we don’t start conserving our energy sources now‚ that is exactly what we will get gas for $6.00 a gallon or maybe even more. In today’s society we are only worried about the here‚ and the now. We all need to start thinking long term and come up with ideas for preserving our future. In the United States the industries use up about forty two percent of the nation’s

Find the dimensions of a rectangle where the altitude is four seventh of of the base and the perimeter is 330 feet. Let x = length of the base x = length of the altitude since the perimeter = 300 Solution: 330 = 2x + 2 ( x)
