# (Originais Teachy 2023) - Question Easy of Physics

As part of her astronomy project, Mary has been observing the moon every night for a month. She noticed that the shape of the moon changes over time. She learned that this is due to the moon's different phases, each lasting approximately 7.4 days. One night, she saw that exactly half of the moon's surface was illuminated. If we consider the new moon (no illumination) as the starting phase, and knowing that the moon takes about 29.5 days to complete a full cycle of phases, how many days would it take for the moon to return to the same half-illuminated phase starting from the new moon?
a.
It would take approximately 22.2 days for the moon to return to the same half-illuminated phase (First Quarter).
b.
It would take approximately 29.5 days for the moon to return to the same half-illuminated phase (First Quarter).
c.
It would take approximately 7.4 days for the moon to return to the same half-illuminated phase (First Quarter).
d.
It would take approximately 37.2 days for the moon to return to the same half-illuminated phase (First Quarter).
e.
It would take approximately 14.8 days for the moon to return to the same half-illuminated phase (First Quarter).
