L = illuminance
A = surface
i = intensity
L = i / A ==: i = L * A
i = 6 lux * 4 m^2 = 24 lumen

Explanation:
Coefficient of linear expansion = 
Length = 0.3 meters
ΔT = Change in temperature = 250 °C
Linear expansion
Change in length of the Pyrex glass dish is 0.000225 m.
Answer:
a) wet marble , dry marble, newspaper, and towel
Answer:
Final temperature of the aluminum = 41.8 °C
Explanation:
We have the equation for energy
E = mcΔT
Here m = 55 g = 0.055 kg
ΔT = T - 27.5
Specific heat capacity of aluminum = 921.096 J/kg.K
E = 725 J
Substituting
E = mcΔT
725 = 0.055 x 921.096 x (T - 27.5)
T - 27.5 = 14.31
T = 41.81 ° C = 41.8 °C
Final temperature of the aluminum = 41.8 °C
Explanation:
well there is nothing there and it could be different by diffrent objects, idk
