Answer:
The answer is:-
Explanation:
An electron emitted from an atom by enteraction with an photon, especially an eclectron emitted from a solid surface by the action of light.
First, calculate volume:
volume = 21.2 ft * 46.1 ft * 19.4 ft
volume = 18,960 ft^3
Convert to gallon:
volume = 18,960 ft^3 * (12 in / 1 ft)^3 * (1 gallon / 231
in^3)
volume = 141,830.71 gallon
Therefore the time is:
time = 141,830.71 gallon / (5.85 gal/min)
time = 24,244.57 min
The work that is done when twice the load is lifted twice the distance is
four times as much
The net work performed by forces acting on an object equals the change in kinetic energy, according to the work-energy theorem.
when an item slows down, the net work applied to it decreases, its change in kinetic energy is negative, and its ultimate kinetic energy is less than its starting kinetic energy. When an item accelerates, positive net work is done on it. All the forces acting on an item must be taken into consideration when determining the net work. You will obtain an incorrect result if you exclude any forces that affect an item or if you add any forces that do not affect it.
Hence The work that is done when twice the load is lifted twice the distance is four times as much

The weight of an object is mass*acceleration. In this case mass*g.
1000*9.8=9800
So the car has a weight of 9800 N.
Answer:
The question is not improper, But I will try to explain your doubt.
- The pot and part of stove are obviously in contact with each other. It is known <em>as conduction</em>
- The pot on gas stove burner, the air above the stove is heated and because it is gas moves upwards, this is <em>convection</em>. The bottom of the pot and surface of the stove are not 100% flat. Thats why there will be little pockets of air underneath the pot,even if you place it on the stove.
If we heat up the stove as much as then it turns to red, this visible sign is known as<em> radiation.</em>
<em>Therefore all the 3 kinds of heat transfer takes place</em>
