What happens when 2 voltages meet?
What happens when 2 voltages meet? This would cause a short-circuit which is basically too low a resistance between two different voltages. THe result is that enough current will try to flow through the resistor to produce the voltage difference at both ends to accomodate their “meeting”. Do voltages in parallel add?

How do you know if an equation has more than one solution?
How do you know if an equation has more than one solution? The equation simplifies to the point that it no longer contains a variable, but expresses a true equation, e.g. 0=0 . For example: 2x+2=2(x+1) simplifies in this way. The equation has an identifiable solution and is periodic in nature. For example: tan2x+tanx−5=0 has […]

How would you prove experimentally the law of conservation of mass?
How would you prove experimentally the law of conservation of mass? Hello, The law of conservation of mass states that during in a physical or chemical change, the mass of products remains equal to the total of reactants. Thus, we obtain Mass of product = Mass of reactants. This verifies the law of conservation of […]
