The "blue" object would look the same. Say that this blue object is a square. That "square" is every color but blue. The only reason that you see it as "blue" is because what we call "blue", it the only color of light that bounces back at our eyes. Under all colors of light, especially simultaneously. This square or any shape for that matter would absorb the other colors of light, but the blue will be rejected. Therefore, we can only see what bounces back at our eyes, which is the color blue in this case.
Hope this helps, WyattMarine501
Answer is D - from the equation of electric field for point charge
Answer:
sorry- but what........?!
Answer:
a.Electric force exerted on one charged sphere, by another charged sphere.
Explanation:
Coulomb's Law describes the electric force between two objects. It is given by the following formula:

The magnetic field surrounding a current carrying conductor is described by Ampere's Law.
Amount of heat generated by a high current flow in a resistor can be described by P = VI
Voltage induced in a coil by a constant magnetic field is described by Faraday's Law.
