The answer is protons(it always has a positive charge)hope that helps. :)
<h3>
Answer:</h3>
Distance = 7 m
Power = 12.5 J/s or watts
<h3>
Explanation:</h3>
Work done = 175 Joules
Force exerted = 25 Newtons
Work done is the product of force exerted and the distance moved by a body.
Therefore;
Work done = Force × distance
Rearranging the formula we can work out the distance;
Distance = work done ÷ Force
= 175 J ÷ 25 N
= 7 m
Thus, the grand piano was moved by 7 m across the living room .
On the other hand,
Power is the rate at which the work is done.
Therefore;
Power = Work done ÷ time
Work done = 175 Joules
Time = 14 seconds
Thus;
Power generated = 175 J ÷ 14 sec
= 12.5 J/s or watts
Hence, a power of 12.5 J/s was generated in moving the grand piano.
Protons because each element has a different number. Example, Oxygen has 8, Nitrogen has 7, Carbon has 6, etc.
<span>Acid rain is precipitation that contains high levels of nitric or sulfuric acid. Natural and industrial sources can release sulfur dioxide and nitrogen oxide into the atmosphere, leading them to combine chemically with oxygen and water to form their respective acidic molecules. These acids are then deposited through rain or dust depending on the climate of the region. While acid rain can occur anywhere in the world, it is prevalent in regions that have high industrial activity.</span>
