Answer:
a)Ek=115759.26J
b)23.15kW
Explanation:
kinetic energy(Ek) is understood as that energy that has a body with mass when it travels with a certain speed, it is calculated by the following equation
for the first part
m=1200Kg
V=50km/h=13.89m/s
solving for Ek
Ek=115759.26J
For the second part of the problem we calculate the kinetic energy, using the same formula, then in order to find the energy change we find the difference between the two, finally divide over time (15s) to find the power.
m=1200kg
V=100km/h=27.78m/s
taking into account all of the above the following equation is inferred
ΔE=
Answer:
see explaination
Explanation:
Balanced equation or stoichiometry equation means in a product after reaction there is no unburned carbon compound left or we can say the oxygen is sufficient to combine with all the carbon and hydrogen moleculs to form Carbon-dioxide and water respectively.
The dew point temperature of balanced equation will be 100°c because water vapour bis present in it and it will condense at 100°c at 1 bar pressure while the other products need much lower temperatures to liquify.
