John goes fishing regularly. He notices that he gets the best catch when the tide is highest, as more fish come close to the shore. Pictured are the Sun-Earth-Moon alignments on four different days. On which two days will John get the best catch?

Answer 1

Taking into account that John gets the best catch when the tide is highest, the best days to go fishing are when the moon is close to the Earth. This is because the gravitational field of the moon has a major impact on Earth when they are close, this means that the moon will try to "attract" the water in the sea, which is the reason why the tide increases, but the moon will never succeed as the gravitational field of the Earth is stronger.
