Never remove a trap with chemicals present; you risk burns to your skin. Call a professional but make certain you inform them of what chemical you used.
Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
But wait a second and think. The Moon follows the Earth around the Sun in its orbit, and if you didnât have the Earth, the Moon would really be orbiting the Sun. So can we say that the Moon is really orbiting the Sun? No. But the case is pretty compelling. First, take a look at the orbital velocity of the Moon. The Moonâs velocity around the Moon is a mere 1 km/second. But the Moonâs velocity around the Sun is 30 km/sec; same as the Earth. And hereâs something stranger. the Moon doesnât follow a spiral pattern around the Sun, as you would think, but it always follows a convex path compared to the Sun.
