Answer:
The difference between reversible and irreversible is reversible can be changed but irreversible can not.
Answer:9.8x10^(-3) w/m°C
Explanation:
Quantity of heat(Q)=14.1w
Distance(d)=2.44cm=2.44/100=0.0244m
Area(a)=1.88m^2
Temperature change(t)=18.6°C
thermal conductivity(k)=?
K=(Qxd) ➗ (a x t)
K=(14.1x0.0244) ➗ (1.88x18.6)
K=0.34404 ➗ 34.968
K=9.8x10^(-3) w/m°C
The distance covered as the crane does work is 76 m.
Recall that the work done in lifting the crane is the product of force and distance covered. In this case, we are talking about the distance through which the crane is raised. Therefore;
Work done = Fs
F = Force applied
s = Distance covered
Substituting values;
Work done/Force applied = Distance covered
Distance covered = 9,500 J/125 N
Distance covered = 76 m
