<span>The conversion for Kelvin from Celsius is simple since the units change at same rate (degree for degree) but haven't different zero reference. The Kelvin scale represents absolute zero. The celcius scale moves degree per degree with kelvin scale but has a zero based on freezing point of water. The conversion is 273 + (temperature in celcius) = temperature on kelvin scale. Note 273 is a rounded number to nearest whole number. The actual figure is a number with decimal. 273.15 can also be used if you want more significant figures.
so 273 + 78C = 351 K </span>
Closest to the sun f thats a choice or closest to the atmoshpere
Answer:
a.0.5 Io
Explanation:
The fraction of light passing through the first polarizer will be
The fraction of light passing through the second polarizer will be
where
= Angle between the filters
here, as the transmission directions are parallel to one another
Hence, 
will pass through both filters
