This is too late too answer?
Answer:
Explanation:
In Carnot engine , temperature difference is used to get work output .
The maximum efficiency of a Carnot engine
= (T₁ - T₂) / T₁
where T₁ is temperature of hot reservoir , and T₂ is temperature of cold reservoir
= efficiency = ( 35 - 4 ) / ( 273 + 35 )
= 31 / 308
in percentage terms
efficiency = (31 / 308) x 100
= 10.06 % .
First recall the equation that relates frequency to wavelength:
v = fw
Note that the v is the speed of light, a constant. Now plug in the information we know!
(3×10^8) = (6.67 × 10^14) w
Hit the numbers on the calculator and you'll get the wavelength, w. If you comment your answer I'll check it for you. :)
The graph shows the production of Fe.
You can see from the graph that it increases rapidly and then slowly increases.
The answer is (A).
Cheers.
No. The DEPENDENT variable is the only one that DEPENDS on
the other one.
The INdependent variable doesn't depend on anything; it doesn't
change until YOU change it.
