Answer:
26.8 %
Explanation:
TH = 100°C = 100 + 273 = 373 K
Tc = 0°C = 273 K
The efficiency of the heat engine is given by
η = 0.268
η = 26.8 %
Thus, the efficiency of the heat engine is 26.8 %.
Answer:
The net friction force is 8.01 N
Explanation:
Net friction force = mass of hockey puck × acceleration
From the equations of motion
v^2 = u^2 + 2as
v = 40 m/s
u = 0 m/s (puck was initially at rest)
s = 30 m
40^2 = 0^2 + 2×a×30
60a = 1600
a = 1600/60 = 26.7 m/s^2
The acceleration of the puck is 26.7 m/s^2
Net friction force = 0.3 × 26.7 = 8.01 N
