Sun powered is the correct answer i believe :)
Answer:
Explanation:
Since it first order, we use order rate equation
In ( ) = -kt where A1 is the final quality = 0.8 (80%), A0 is the initial quality = 1 ( 100%)
also, t half life = where k is rate constant
k = = 0.0154
In ( ) = - 0.0154 t
-0.223 / -0.0154 = t
t = 14.49 approx 14.5 days from the date the yogurt was packaged
Kcal=1000 cal
Min=60 sec
0.74 *1000= 740cal/min
740 cal/min /60= 12.333 cal/s
