The answer is 0.04 this is the answer you walcome
The term used for the total radiation that is reflected by a surface is albedo. It is the percent of solar energy that is being reflected from our Earth back into the space. It is a dimensionless value since it is a percentage and ranges from a value of zero (corresponds to a perfect black body where it absorbs all of the radiation) to one (corresponds to a white body where all radiation is being reflected). This term is very useful in astronomy, climatology and environmental management. The average albedo of Earth is found to range from 30 percent to 35 percent due to the clouds present in the atmosphere.
Answer: (C) the electrons in the glass completely fill its valence levels and can’t shift from one level to another to transport charge through the glass.
Why: The electrons in an insulator such as glass completely fill the valence levels. Since only two electrons, one spin-up and one spin-down, can be in any level, the valence can't accommodate any shift in electrons from one level to another. The electrons can't respond to any electric fields and they can't conduct electricity.

Density = Mass/Volume
=> 5g/cm³ = 45kg/Volume
=> 0.005kg/cm³ = 45kg/Volume
=> Volume = (cm³×45kg)/0.005kg
=> Volume = 9000kg/cm³
Answer:
110.27 m/s or 396.972 km/h
Explanation:
F = Force
m = Mass = 84 kg
g = Acceleration due to gravity = 9.81 m/s²
C = Drag coefficient = 0.7
ρ = Density of air = 1.21 kg/m³
A = Surface area = 0.16 m²
v = Terminal velocity
F = ma
Converting to km/h
Terminal velocity of the skydiver is 110.27 m/s or 396.972 km/h
