Answer:
There's a formula for finding the coefficient of friction i.e. μ = f÷N
hope it helps!
W zener = Vz x Iz max.
Iz max = 1/5 = 0.2 A = 200 mA
<span>Efficiency is the measure
of how efficient a process is. It is used to assess the ability of a process in
avoiding waste energy, materials, money and time in doing a desirable output.
It is calculated in thermodynamics as:
Efficiency = 1 - Tc / Th
</span>Efficiency = 1 - 210 / 490
Efficiency = 0.57
