The law of moments is when an object is balanced; the sum of cloclwise moments is equal to the sum of counter clockwise moments. I hope this helped, Enjoy the rest of your day
Answer:
The efficiency of Carnot's heat engine is 26.8 %.
Explanation:
Temperature of hot reservoir, TH = 100 degree C = 373 K
temperature of cold reservoir, Tc = 0 degree C = 273 K
The efficiency of Carnot's heat engine is
The efficiency of Carnot's heat engine is 26.8 %.
To develop this problem it is necessary to apply the concepts related to the angular resolution of a telescope as well as to the arc length.
The arc length can be defined as
Where
r= Radius
\theta = Angle
At the same time the angular resolution of a body is given under the proportion
Where
= Wavelength
D = Diameter
Our values are given as
Then the angle of separation of the two objects seen from the observer is of
Finally, using the proportion of the arc length, in which we have the radius and angle we can know the separation of the two objects by:
Answer:
3.388888888 or 3.4 (rounded)
Explanation:
Divide 225 / 25
225/25= 9
