Answer:
ΔS = 3.09 J/K
Explanation:
Entropy is defined as the magnitude of disorder in a system. Mathematically, entropy change is given as, the heat absorbed or released by a system divided by the change in absolute temperature. So, the formula for entropy change is as follows:
ΔS = ΔQ/ΔT
where,
ΔS = Change in Entropy of Metal Wire = ?
ΔQ = Heat Conducted through Wire = 1216 J
ΔT = Difference in Temperature = 686 K - 292 K = 394 K
Therefore,
ΔS = 1216 J/394 K
<u>ΔS = 3.09 J/K</u>
Our modern version which is a heliocentric model of the universe also supported by other scientists like Nicholas Copernicus and Johannes Kepler developed theories that conflicted with the Ptolemaic model of the universe developed by Ptolemy in ancient times which assume that the earth is the center of the solar system and all the stars and planets are revolving around it.
<h3>What is a solar system?</h3>
It is a system that collection of all the planets and spatial bodies revolving around the sun because of the gravitational pull of the sun.
Our Solar System is based on a heliocentric model in which the Sun is assumed to reside at the central point of the planetary system.
In other words, the Sun is at the center while the Earth and other planetary bodies revolve around it.
The geocentric model of the universe developed by Ptolemy in ancient times, which holds that the earth is the center of the solar system and that all the stars and planets revolve around it, was in conflict with our modern version, which is a heliocentric model of the universe and also supported by Nicholas Copernicus and Johannes Kepler.

Answer:
Resistance is a measure of the opposition to the flow of current in an electrical circuit.
Explanation:
It is symbolized by the Greek letter omega (Ω), resistance is measured in ohms.
If an electric current of one ampere passes through a component across which a potential difference (voltage) of one volt exists, then the resistance of that component is one ohm
Answer:
length
Explanation:
used to measure outer dimensions of objects
