Artificial satellites are used to study the Earth, other planets, to help us communicate, and even to observe the distant Universe. Satellites can even have people in them, like the International Space Station and the Space Shuttle. The first artificial satellite was the Soviet Sputnik 1 mission, launched in 1957.

May consider a group g=({0,1},+)g=({0,1},+)where ++ will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are called ‘00’ and ‘11’ and may not mean zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself. for a set ss in g′g′ having more elements than just {0,1}{0,1} the values for a+b∈sa+b∈s, such that a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of 1+11+1. the answer could possibly have been 22 if oanswer is25,000

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
