0.02020 ohm is the resistance of a carbon rod at 25.8 ∘C if its resistance is 0.0200 Ω at 0.0 ∘C.
<h3 /><h3>What is a resistor?</h3>
A resistor is an electrical component that controls or restricts how much electrical current can pass across a circuit in an electronic device. A specified voltage can be supplied via resistors to an active device like a transistor.
The temperature of the resistor varies based on the variation in the temperature. The equation that describes the relationship between the two of them is:
R = R0[1+ alpha(T-T0)] where:
R is the new resistance we are looking for
alpha is the temperature coefficient of resistance. For carbon rod, alpha = ₋ 4.8 x 
(1/°c)
T0 is the standard temperature =25.8°C
R0 is the resistance at T0 = 0.0200 ohms
T is the temperature at which we want to get R = 0
Substitute in the equation to get R as follows:
R = 0.0200 [1+( ₋ 4.8 x ) (0-25.8)] = 0.02020 ohm

Saturn It is most well-known for its rings.
Neptune It has the strongest winds in the solar system.
Uranus its orbit was used to predict the existence of another planet.
Jupiter It has a giant storm three times the width of Earth.

<u>Properties of different planets</u>
Saturn is the second largest planet in the solar system and it’s most well-known for its bright and beautiful rings that circle its equator. These rings are composed of numerous ice and rock particles
Neptune has the strongest winds in the solar system and the winds are known for whipping the clouds at a speed of approximately 2000 Km/h
Astronomers used the orbit of Uranus to predict the existence of Neptune in 1846.
Jupiter has an iconic Great Red Spot just off the planet’s center which is approximately 1.3 times the Earth’s diameter and its winds move at a speed approximately 425 mph.
Certain electrons in the dye molecule move to a higher energy level, with the difference in energy between the lower and higher energy levels being the same as the energy of the absorbed photons.
