Answer:
Explanation:
given,
Temperature of heat engine operate between
Th (temperature in hot reservoir) and Tc(temperature in cold reservoir)
amount of heat released to = Qc
to find maximum amount of work = ?
now,
efficiency of heat engine
now,
maximum work =
above expression gives the expression of maximum amount of work.
A
<span>(Volatile liquids, liquids with a high vapor pressure or low boiling point) </span>
Answer:
B 23m/s
Explanation:
From the above information we get,
Initial velocity= 3m/s
Acceleration by gravity = 10 m/s2 (approx)
Time taken =2 seconds
v=u+at (First Equation Of Motion)
v= 3 + 10 × 2
v= 23 m/s
