1.

The surface temperature oscillates about the mean temperature level in accordance with the relation

A. α <sub>S,T</sub> – α <sub>S,A</sub> = 2 sin (2 π n T)
B. α <sub>S,T</sub> – α <sub>S,A</sub> = 5 sin (2 π n T)
C. α <sub>S,T</sub> – α <sub>S,A</sub> = sin (2 π n T)
D. α <sub>S,T</sub> – α <sub>S,A</sub> = 3 sin (2 π n T)
Answer» D. ‚âà√≠¬¨¬± <sub>S,T</sub> ‚Äö√Ñ√∂‚àö√ë‚àö¬® ‚âà√≠¬¨¬± <sub>S,A</sub> = 3 sin (2 ‚âà√¨‚àö√ë n T)
