Answer:
Explanation:
Atomic mass of hydrogen is 1 . so 1 g of hydrogen will have 6.02 x 10²³ atoms
3 g of hydrogen will have 3 x 6.02 x 10²³ atoms . This will give 3 x 6.02 x 10²³ protons and same number of electrons
So number of protons at north pole = 3 x 6.02 x 10²³
charge on these protons = 1.6 x 10⁻¹⁹ x 3 x 6.02 x 10²³ C
= 28.9 x 10⁴ C
similarly total charge on electrons at south pole = 28.9 x 10⁴ C
distance between them = diameter of the earth = 2 x 6356 x 10³ m
= 12712 x 10³ m
Attractive force between these charges
= k q₁q₂ / r² , q₁ ,q₂ are charges and r is distance between charges.
= 9 x 10⁹ x (28.9 x 10⁴)² / (12712 x 10³ )²
= 4.6517 x 10⁻⁵ x 10¹¹
= 4.6517 x 10⁶ N
The gravity of the Sun keeps the planets in their orbits rotating. The same as the Moon orbits the Earth because of the pull of earth's gravity, the earth orbits the Sun because of the pull of the Sun's gravitational pull.

Answer:if you know the history, you know the best dig site in a way where you know your roots and where the best place is.
Explanation:let’s say that if someone was going on a trip to a foreign country, they would do a little research to know what they were expecting. Similarly, if you were picking a Destiination for your dig site, you would have to do a little research for example, like the earths history to know where the greatest treasures you could find and make the most discoveries while in your dig site.
