<em>Due to the shortcomings in Piaget’s approach to cognitive development several other theories were put forward.</em>
<u>Explanation:</u>
Jean Piaget is the psychologist that offered explanations about cognitive development in children. There were several shortcomings in his theories and thus alternative theories about cognitive <em>development in children </em>were developed.
<em>Lev Vygotsky</em> proposed another explanation to children’s cognitive development. He strongly emphasized on the influence of culture on <em>children’s cognitive development</em>. He believes that it is through socio-cultural interactions development progresses.
He believed that individualized thoughts begin after these interactions. He take on <em>self-speech </em> was different from Piaget. Vygotsky considered self-speech as a guide to thinking while Piaget thought <em>self-speech to be egocentric. </em>
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>
