The efficiency of a heat engine is given by the expression 
The efficiency of a heat engine is the ratio of the work done by the engine to the heat given as the input to the engine.
The heat engine absorbs Q h from the hot reservoir , performs a work <em>W</em> on the absorbed heat and rejects Qc to the cold reservoir.
Therefore, the work done is given by,
Thus the efficiency is given by,
Answer:
34.45m
Explanation:
Using the equation of motion formula v² = u²+2as to get the distance travelled
v is the final velocity = 26m/s
u is the initial velocity = 0m/s
a is the acceleration due to gravity = 9.81m/s²
S is the distance travelled
Substituting the given values into the formula;
26² = 0²+2(9.81)s
676 = 0 + 19.62s
19.62s = 676
s = 676/19.62
s = 34.45m
Hence the distance she would travel during the race is 34.45m
Relative motion is the calculation of the motion of an object with regard to some other moving object.
