The eclipse usually moves from west to east as the moon rotates the Earth from west to east and the Earth rotates towards the east as well.
This means that the shadow of the moon is also moving towards the east. That's why the eclipse moves towards the east (it follows the lunar shadow).
That makes no sense I can't help sorry
Answer:
Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.
Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.
Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.
Nonmetals are plentiful and useful. These are among the most commonly used:
Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.
Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.
Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.

(b) The Planck time is given as
T=
=5.39×
of the same order of magnitude as the ultra hot epoch
<h3>What exactly is Planck Time?</h3>
- The Planck time is the fundamental unit of time in the Planck Unit system. It has the following worth:
- =5.39×
- Measurements of time in SI units are made in seconds (usually given the symbol s). Although measuring the time it takes an athlete to sprint 100 meters or the length of a phone call in seconds is convenient in everyday life, it becomes less practical when discussing the sequence of events that occurred in the very early Universe (such as the onset of inflation that occurred 10-35s after the Big Bang).
- The entire geometry of spacetime predicted by general relativity breaks down at this scale. As a result, to describe the laws of physics on such scales, an as-yet undiscovered theory combining general relativity and quantum mechanics is required. As a result, our current descriptions of the Universe's early evolution begin at =5.39× seconds after the Big Bang.
