Answer:
Explanation:
Evaporation results in cooling because water absorbs heat equal to mass times latent heat of evaporation to get converted into vapor .
latent heat of evaporation of water = 2260 x 10³ J / kg or 2260 J / g
in the evaporation of 1 g of water , heat lost = 2260 J
heat lost per minute = 2260 J
heat lost per second = 2260 / 60
= 37.66 J /s
= 37.66 W
So heat lost by dog in watt = 37.66 W.

Detergents are special, powerful cleansers that can break up dirt, oils, and grease in clothing or on dishes.
Cleaning solvents are used to remove oil, grease, solder flux, and other contaminants.
Acid cleaners are generally used to remove mineral deposits and are useful for descaling dishwashers or removing rust from restroom facilities.
Abrasive uses
* Buffing.
* Honing.
* Drilling.
* Grinding.
* Sanding.
* Polishing.
* Cutting.
* Sharpening.
From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.
Answer:
The length of the wire is 2.86 m
Explanation:
Given:
Current A
Magnetic field T
Force N
Angle between wire and magnetic field 46°
The magnetic force on the current carrying wire is given by,
Where length of wire
m
Therefore, the length of the wire is 2.86 m
