Answer: T = -0.213°c
Heat flow = 38.2 w/m²
Explanation:
given data:
Wood = 0.031m thick
Styrofoam = 0.023m thick
Wood = k ( 0.080W/m.k)
Styrofoam = k (0.010W/m.k)
Temperature of wood = -15°c
Temperature of styrofoam = 19°c
(a) heat flow in wood and styrofoam must be equal
KAdT/ L = KAdT/ L
0.080 * A * ( T - ( -15) ) / 0.031 = 0.010 * A * ( T - ( 19°c) ) / 0.023
T = -0.213°c
(b) heat flow
H = KAdT / L
H = 0.080 * A * ( -0.213°c - ( -15°c) ) / 0.031
= 38.2 w/m²
Not sure this is a physics question (probably biology).
Anyway, the correct answer is A):
"Plasticity helps us to adapt to our environment. It also generally decreases with age".
Plasticity is the ability to adapt to the environment. Since this ability is linked with brain functions, and brain functions worsen with age, then plasticity decreases with age.
