Answer:
The efficiency is 0.33, or 33%.
Explanation:
From the thermodynamics equations, we know that the formula for the efficiency of a heat engine is:
Where η is the efficiency of the engine, Q_1 is the heat energy taken from the hot source and Q_2 is the heat energy given to the cold object. So, plugging the given values in the formula, we obtain:
This means that the efficiency of the heat engine is 0.33, or 33% (The efficiency of an engine is dimensionless).
Answer:
-22/15
Explanation:
the least common denominator is 15 so first you multiply -2/3 by 5 in both the numerator and denominator making it -10/15
Then you do the same to -4/5 except you multiply the numerator and denominator by 3 giving you -12/15
If you add -10/15+ -12/15 you get -22/15
A pull between two objects, for example, between an object and Earth. When forces on an object are balanced, there is no change in speed or direction.
So the answer is I agree
Answer:
$18
Explanation:
Each of the was qiven $18
All together =24
24 divide it by 4 (because there were 4 people there)
= 6 (6+6+6+6)
= 24
=6+12=18
.Hence each of them was given $18
