What has become an important alternative to Piagetian approaches?
Mice21 [21]

<u>Answer:</u>

<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>

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75-kg (165-lb) person o
CaHeK987 [17]

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:

Q = \sigma A (T^4 - T_{s}^4)\\

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,

Q = (5.6703\ x\ 10^{-8}\ W/m^2.k^4)(2\ m^2)[(303\ k)^4-(291\ k)^4]<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,

Q = (0.8)(Basal\ Metabolic\ Rate)\\Basal\ Metabolic\ Rate = \frac{Q}{0.8}\\\\Basal\ Metabolic\ Rate = \frac{142.67\ W}{0.8}

<u>Basal Metabolic Rate = 178.33 W</u>
