Explanation:
The formula for gravitational force (F) is
where m and M are the masses of the two objects, d is the distance between their centres, and G is the gravitational constant.
If we hold m, and M constant, we can write
where k = Gmm
Thus, gravitational force is inversely proportional to the square of the distance between the objects.
Let d₂ = the radius of the planet
And d₁ = the radius of the Earth. Then
d₂ = 2d₁

A spit is an extended stretch of beach material that projects out to sea and is joined to the mainland at one end.

Answer:
Each province is unique. Data published recently by Stats SA provide a portrait of South Africa’s provincial economies, so below is a fact facts about our economic landscape.
Fact #1 Gauteng is South Africa’s economic powerhouse
Don’t let Gauteng’s size on a map fool you. It might be the province with the smallest land area, but economically it packs a punch. Gauteng generated just over a third of South Africa’s gross domestic product (GDP) in 2017, making it the nation’s biggest provincial economy .KwaZulu-Natal was the second biggest, responsible for R16 of every R100 generated by the national economy. Northern Cape, the smallest provincial player, would need to multiply its economic output by 17 in order to square up against Gauteng.
Gauteng’s economic dominance is not surprising. Finance, government, manufacturing, construction and four other industries are heavily represented in the province.
Agriculture and mining are the two exceptions. National agriculture production is mostly concentrated in Western Cape and KwaZulu-Natal. The bulk of national mining activity takes place in North West, Mpumalanga and Limpopo.so there was one fact.
