Answer:
Explanation:
Given
Resistor A has length ![L_1](https://tex.z-dn.net/?f=L_1)
and Resistor B has Length ![L_2](https://tex.z-dn.net/?f=L_2)
and Resistance is given by
![R=\frac{\rho L}{A}](https://tex.z-dn.net/?f=R%3D%5Cfrac%7B%5Crho%20L%7D%7BA%7D)
Considering
and A to be constant thus
because ![L_2>L_1](https://tex.z-dn.net/?f=L_2%3EL_1)
(a)When they are connected in series
As the current in series is same and power is ![i^2R](https://tex.z-dn.net/?f=i%5E2R)
therefore
as R is greater for second resistor
(b)if they are connected in Parallel
In Parallel connection Voltage is same
![P=\frac{V^2}{R}](https://tex.z-dn.net/?f=P%3D%5Cfrac%7BV%5E2%7D%7BR%7D)
resistance of 2 is greater than 1 thus Power delivered by 1 is greater than 2
A comet is the loose, icy body with a long, narrow orbit.
Comets are very small solar system body made mainly of ices mixed with smaller amounts of dust and rock. Most comets are not larger than a few kilometers across. The main body of the comet is called the nucleus, and it can contain water, methane, nitrogen and other ices. Their speeds vary depending on their orbits and where they are in it. The closer they are to the sun, the faster they are going.
<span>The two foremost forces that were involved in the creation of the Cascade mountains are those of the tidal and tectonic forces. Tidal forces helped in eroding anything that was there previously, and the tectonic forces caused the eruption of these mountains to take place.</span>
Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire. Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment.
Answer:
1. the voltage will be 2.35×12.5 = 29.4V
2. the resistance would be 9.0/6.2= 1.45ohms
3. in series they will add up thus 4+8+12= 24ohms
4. in parallel it will be 2.18ohms
