The Eclipses only occur one more time during the year 2025, and that is on September 7th (Lunar) and September 21" (Solar). If we have a full moon and a new moon every month, why do you think we can't see a lunar and solar eclipse every month?

How does the idea of rotating disk in the nebular model explain certain observed celestial phenomena?

The velocity of the transverse waves produced by an earthquake is 8.9 km/s, and that of the longitudinal waves is 5.1 km/s. A seismograph records the arrival of the transverse waves 68 s before the arrival of the longitudinal waves.
