<span>THERMAL EQUILIBRIUM
this state is called thermal equilibrium
when 2 bodies initially at different temperatures r brought together heat flows from the hotter body to colder body until both the bodies r at the same temperatures</span>
Answer:
... As has been previously discussed, heat is not something that is contained in an object.
Explanation:
Felicia** drove at 45 mph. After 1/3 of an hour, when her husband started out, she was (45/3) = 15 miles from home.
Husband drove at 55 mph. He gained (55-45) = 10 miles on Felicia each hour. That is, he closed 10 miles of the gap each hour.
It took him (15/10) = 1.5 hours to catch up to her.
That's <em>1hr 30min after HE started out</em>, and <em>1hr 50min after SHE left the house</em>.
** I've spelled the wife's name as 'Felicia' throughout my solution. I'm pretty sure there's a better chance of this being the correct spelling rather than 'Felecia', and I never trust anybody who can't spell their own name.
A plane figure with at least three straight sides and angles, and typically five or more.Polygon-
Consecutive vertices-The endpoints of one side of a polygon.
diagonal of a polygon
A polygon with all the angles equal and all the sides equal.
regular polygon
Any closed figure bounded by three or more segments that only intersect at their endpoints. The segments are called the sides, and the endpoints are called the vertices of the polygon.
