Given: Heat Qout means useful work = 2800 J
Heat Qin = 8900 J
Required; Efficiency = ?
Formula: Efficiency = Qout/Qin = x 100%
= 2800 J/8900 J = 0.3146 X 100 %
Efficiency = 31.46%
Hey :)
The water potential of pure water<span> in an open container is zero because there is no solute and the pressure in the container is zero</span>
Answer:
I think your answer would be D
Explanation:
Answer: Released
Explanation: Energy is released in this reaction possibly in the form of heat thus it is an exergonic and or exothermic reaction.
Answer:
v=u+at
24=0+at
24=a×6
a=4m/s
hence
s=ut+at^2÷2
s=36m
Explanation:
since the car is brought to rest the u=0
