The answer is a negative externality
The correct answer is B. Tan was proud of her mother who had a unique way of communicating in English language that is why in her book she chooses to discuss about her mother.
Tan and her mother they had a close relationship because,
1. Tan's mother used to attend tans lectures.
2. Her mother trusts and relies on her to talk to doctors about the scan of CAT.
Tan is the author of this essay which is entitled as the" mother tongue". The message of Tan's essay is that communication is more about intent and not specific word and words usage.
We have the following assumptions:
The temperature of the surroundings remains constant.
The entire surface area of head emits radiation.
From the problem, we have the given values:
emissivity = 0.95
T2 = 36 degrees C
T1 = 9 degrees C
Solving for the area:
A = πD² + πDh = π(21)² + π(21)(20) = 2709.91 cm² = 0.2710 m²
Using the heat transfer equation for radiation:
q = εAσ(T₂⁴ - T₁⁴)
q = 0.95 (0.2710)(5.67 x 10<span>-8)[(36+273)</span>⁴-(9+273)⁴]
q = 3.9 x 10^9 W
