<em>Scientific method </em>is basically the process for experimentation used for observing– and is in any investigation in which a hypothesis is scientifically tested.
Answer:
Correct answer is Athens and Sparta both used slaves, but Athenian men would work with the slaves.
Explanation:
First option is correct, as in Sparta slaves were owned by state and were practically seen as tools, while in Athens slaves were private ownership, and were treated more fairly, and would be even able to gain their freedom. Some would say that it was sometimes even hard to differ slaves from freeman.
Second option is not correct as there were slaves in both countries.

Fourth option is also not correct as in Athens they were used for many purposes.

Explanation:
South Africa is the only country of Africa which has nuclear plant.
2 location of nuclear power plant are
i)Koeberg nuclear power station which gives 5%of south Africa electricity.
ii) Pelindaba nuclear research center in Gauteng.
The effect and disaster of nuclear power:-
There are early conception of nuclear power for the failure of machine and human error which lead to tremendous effect on the surroundings.
If once by mistake nuclear power exposed to environment it creates natural hazards, such as hurricanes, tsunamis, floods, fires, earthquake, volcano. So to keep safety it always have vital key role for engineers. They always consider well architecture, structure, design, site for making the power plant to minimize its disaster to our environment.
A globular cluster is a collection of stars in the form of a sphere that orbits a galactic core. Global clusters are generally tightly bound by gravity, making the stellar density higher toward the center, and giving them their spherical shapes. Globular clusters are usually found in the halo of a galaxy.
The fact that the gravitational pull of a globular cluster is rather weak means that a single supernova explosion can blow the interstellar gas out of a globular cluster. This would mean that the gas left is not dense enough to form new stars. After the first generation, globular clusters cease to form new stars because they lack material due to their deficiency in heavy elements.
