Rasek [7]3 years ago
3 0

Answer:

Assume I1 = Io * T1        transmission proportional to thickness

I2 = Io * T2          I is intensity of light absorbed     (3/8 absorbed)

I1 / I2 = T1 / T2

T2 = T1 * (I2 / I1) = 2 * (2/3 / 3/8) = 2 * 16/9 = 32/9   thickness for 2/3 absorbed

A thick window pane 0.367 cm has an area of 1.247 square meters. The temperature difference between the inside and outside surfa
____ [38]

Answer:

B. 9025 J/s

Explanation:

thickness (d) = 0.367 cm = 0.00367 m

area (A) = 1.247 m^{2}

temperature difference (ΔT) =33.2 °C

thermal conductivity (K) = 0.8 J/s/m/°C

find the rate of heat flow

rate of heat flow = \frac{K.A.ΔT}{d}

rate of heat flow = \frac{0.8x1.247x33.2}{0.00367}

rate of heat flow = 9024.6 ≈ 9025 J/s

When we say that an object wants to maintain its state of motion, we’re talking about inertia. Which term determines the quantit
Salsk061 [2.6K]
I think it's velocity, because when an object stands in inertia, or it has velocity equals to zero, or it has constant velocity because there is no friction to stop the object.
