Answer:
(a) Q = 142.67 W
(b) Basal Metabolic Rate = 178.33 W
Explanation:
(a)
We can find the heat radiated by the person by using Stefan-Boltzman's law:
where,
Q = heat radiated per second = ?
σ = Stefan-Boltzman Constant = 5.6703 x 10⁻⁸ W/m².k⁴
A = Surface Area = 2 m²
T = Temperature of Skin = 30° C + 273 = 303 k
Ts = Temperature of room = 18° C +273 = 291 k
Therefore,
<u></u>
<u>Q = 142.67 W</u>
<u></u>
(b)
Since the heat calculated in part (a) is 80 percent of basal metabolic rate. Therefore,
<u>Basal Metabolic Rate = 178.33 W</u>

Answer:
Explanation:
<em>Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.

<em>
</em>
<em>(E) that have a comparable size, as well as emitting far fewer of the other gasses having</em>
<em>A is the most appropriate statement above. Diesel engine consume less energy and release fewer gases than the gasoline engines .</em>
<em>Both engine(Diesel and gasoline) converts chemical energy to electrical energy.</em>
Answer:
c. As the thread is stretched, the coating thins and its resistance increases; as the thread is relaxed, the coating returns nearly to its original state.
Explanation:
This is in line with the result as shown in the data.
Stretching causes the coating to thin which in turn increases the resistance of the thread (conduction drops) releasing it backs returns the thread to nearly its initial values, but due to the strain already in the thread it does not return to its original values.
Elliptical, because the shape of the galaxy isn’t like the others. It is unique to its own and doesn’t have another to compare to
