Answer:
Power, P = 924.15 watts
Explanation:
Given that,
Length of the ramp, l = 12 m
Mass of the person, m = 55.8 kg
Angle between the inclined plane and the horizontal, 
Time, t = 3 s
Let h is the height of the hill from the horizontal,
h = 5.07 m
Let P is the power output necessary for a person to run up long hill side as :
P = 924.15 watts
So, the minimum average power output necessary for a person to run up is 924.15 watts. Hence, this is the required solution.
Answer:
Combustion reaction resulted in formation of Hydrogen gas.
Explanation:
When zinc and Hydrogen Chloride (HCl) are mixed together, it is a oxidation reduction process. To be specific, a combustion reaction takes place. It is an exothermic reaction. Exothermic reactions involve oxygen and generate . Here, due to this exothermic reaction, Hydrogen gas is being produced which results in the formation of bubble and inflation of balloon.
