Nothing happens. The frequency is determined at the source,
and it doesn't change along the way.
Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire. Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment.
Answer:
In a single replacement reaction, one element takes the place of another in a single compound. In a double replacement reaction, two compounds exchange elements. A combustion reaction occurs when a substance reacts quickly with oxygen. Combustion is commonly called burning
P=4800kgm/s
As
p=mΔv
where p is momentum, m is mass and v is velocity
Given values is
m =1200kg
Δv= 17m/s-13m/s=4m/s
Now
p=mΔv
p=(1200kg)*(4m/s)
p=4800kgm/s
