Answer:
a. Air fuel Ratio = 19.76 kg air/kg fuel
b. % Theoretical air used = 131%
c. Amount of H2O that condenses as the products are cooled to 25°C at 100kPa = 6.59 kmol
Explanation:
Answer:
t = 1.084 s
s = 8.25 m
Explanation:
given,
height from where skate board start (h) = 1 m
speed = 7.6 m/s
we know
v² = u² + 2 g h
v² =7.6² + 2×9.81× 1
v = 8.79 m/s





t = 1.084 s
then horizontal distance


s = 8.25 m
Answer:
Coolant absorbs thermal energy
Explanation:
Since the coolant is used to refrigerate the engine, it have to absorb the thermal energy
Answer:
Static friction
Explanation:
When there is contact between two surfaces and there is no movement, there is static friction. So, if we have a book that rests on a wooden table, we have an example of Static friction, where this force avoids the movement of the book.
Answer:
Potential, Kinetic and Chemical energy.
