Answer:
<em>0.01 W</em>
<em></em>
Explanation:
diameter d of rod = 4 mm
radius r of the rod = d/2 = 4/2 =0.002 m
length L of rod = 100 mm = 0.1 m
temperature of rod = 455 °C
temperature in kelvin = 455 + 273.3 = 728.3 K
emissivity ε of rod = 0.5
external radiative surface area of rod is calculated as
A = 
= 3.142 x 
x 0.1 = 1.26 x 
m^2
<em>Power dissipiation P = εσA(</em>
<em>)</em>
where σ Stefan's constant = 5.67 x 
W-
-
P = 0.5 x 5.67 x x 1.26 x x 
= <em>0.01 W</em>
Answer:
Option E
The planning and construction of the resorts represent an impact lag of this policy.
Explanation:
Whereas the legislation was enacted without any delay but planning takes six months and construction taking 2 months, it means the policy has a lag. Therefore, option E, the planning and construction of the resorts represent an impact lag of this policy.
