Answer:
The temperature of cold reservoir should be 246.818 K for efficiency of 35%
Explanation:
In first case we have given efficiency of Carnot engine = 26 % = 0.26
Temperature of cold reservoir
We know that efficiency of Carnot engine is given by
For second Carnot engine efficiency is given as 35% = 0.35
And temperature of hot reservoir is same so
So
So the temperature of cold reservoir should be 246.818 K for efficiency of 35%
D. Number of components
22583.5J
KE=1/2 mv^2
=1/2*47Kg*(31m/s^2)
=23.5Kg * 961m/s^2
=22583.5J
34.45m
Magnitude of a vector is equal to the square root of sum of squares of x & y vectors.
Magnitude =
=
=34.45m
