Answer:
resistances is inversely proportional to the area of cross section of the conductor
With an average surface temperature of about 737 K, Venus is the hottest planet.
While Mercury is closest to the sun, it has gaseous molecules that protect it. Venus is the second closest planet to the sun, and is the hottest planet.
Steam<span> is water in the gas phase, which is </span>formed<span> when water boils. </span>Steam<span> is invisible; however, "</span>steam<span>" often refers to wet </span>steam<span>, the visible mist or aerosol of water droplets </span>formed<span> as this water vapour condenses.
hope this helps plz give brainliest!</span>
Solid substances have molecules held tightly and close together
Liquid substances have molecules moving loosely
Gaseous molecules are moving completely freely
As moleclues get further apart, i.e. As a substance changes state from solid to liquid to gas, molecules gain kinetic energy and vibrate/move more. This means they gain heat energy (the averge energy a substance has) so the temperature increases
Substances exist in different states at different temperatures and different substances will exist in different states at the same temperature. This is to do with the forces between molecules and how much heat (energy) is required to break them
Answer:
4.5 N upward
Explanation:
You take the net force and subtract it from the weight
