Because these both are different quantities,one is gravitational acceleration while other is the proportionality constant."g" can vary as it is the rate of change of velocity of any mass over which gravitational force is acting."g" changes due to different factors,like altitude etc.But "G" being a constant has non variable value.
Waves in which the vibrations swing back and forth perpendicular to the direction that the wave travels are called transverse waves.
Answer: Option B
<u>Explanation:
</u>
In the transverse waves, the displacement of particles is perpendicular to wave propagation's direction. The particle does not move with the waves; when the wave passes, they simply oscillate up and down in individual equilibrium positions.
In Earthquake, S waves (secondary waves) are the best example to the transverse wave. S waves spread more slowly than P waves and later arrive in a few seconds. A classic example, the wave from a long rope. The waves move from rope’s one end to the end of other, but the real rope goes up and back, not like a wave from left to right.
The moon's orbital plane is different from that of the earth's orbit around the sun due to which lunar and solar eclipses do not occur every month.
<h3 /><h3>What is a solar eclipse?</h3>
When the moon passes in front of Earth and the sun, it creates a solar eclipse and casts a shadow across the globe.
Only during the new moon phase, when the moon travels squarely between the sun and Earth and casts shadows on its surface, can a solar eclipse occur.
Due to the moon's orbit being five degrees off-center from Earth's orbit around the Sun, lunar eclipses do not happen every month and the Moon often passes above or below the shadow.
Lunar eclipses would happen every month if there were no tilt. Eclipses of the sun and the moon happen equally often.
Hence lunar and solar eclipses aren't coming every month.
