No.
Explanation:
= Power rating = 1 W
R = Resistance =
V = Voltage =
Power is given by
So
Hence, the resistor is not operating within its power rating.
Answer:
The height of the water is 1.25 m
Explanation:
copper properties are:
Kc=385 W/mK
D=20x10^-3 m
gc=8960 kg/m^3
Cp=385 J/kg*K
R=10x10^-3 m
Water properties at 280 K
pw=1000 kg/m^3
Kw=0.582
v=0.1247x10^-6 m^2/s
