No, John's cousin would not see the same phase of the moon in New York. The phase of the moon can vary depending on the location and time of observation. While John sees the moon as a waxing gibbous in China, his cousin in New York may see a different phase of the moon, depending on the time and location of their observation.
Yes, John's cousin would see the same phase of the moon in New York as John sees in China. The phases of the moon are determined by the positions of the sun, earth, and moon relative to each other. Although the exact position of the moon in the sky may vary slightly due to the observer's location on Earth, the moon's phase is visible from all locations on the same day. Therefore, if John sees the moon as a waxing gibbous in China, his cousin in New York would also see the same phase of the moon.
