Explanation:
Temperature is Kelvin, Mass is Kilograms, Length is Meters and Electric current is Ampere.
Hence the answer is C.
The ozone layer filters out harmful ultraviolet radiation which makes the third option correct. It filters out harmful radiation from the sun.
Fnet=(115+106)-186= 34 N
mass=Force/g= 186N/9.8m/s^2 = 18.98 kg
a=fnet/mass => 34N/18.98kg = 1.79 m/s^2
so A= 1.8m/s^2
