Answer:
Explanation:
The equation is balanced because the mass and charge are equal on both sides of the reaction equation.
In a nuclear reaction, one nucleus is transformed into another. In this case of the equation shown, the radon nucleus is being transformed into a polonium nucleus with the emission of an alpha particle.
The equation is balanced because a total mass of 219 is found on both sides of the reaction equation and a total charge of 86. Recall that an alpha particle is the same as a helium nucleus with a mass of four units and a charge of two units.
When you have a fraction, you can make it into as many equivalent fractions as you want, there is an infinite number of possibilities. As long as you multiply both the numerator and the denominator by the same number, the fraction will be equivalent. For example. If you multiply it by 2, you'd get 8/10. By three would be 12/15. By 4 would be 16/20 and so on and so forth. Hope this helped!

Explanation:
If several resistors are connected in series in an electric circuit, the potential difference across each resistor, the current, varies directly with its resistance.
<h3>What is a resistor?</h3>
A resistor is a used to control the flow of electricity in an electric circuit. They are made up of carbon or copper, which resist the flow of charge.
The total resistance across all the component, in a series circuit, increases with adding of more component.
Thus, If several resistors are connected in series in an electric circuit, the potential difference across each resistor, the current, varies directly with its resistance.
