<span>The stars change position in the sky through the course of the night just like the sun changes position in the sky through the course of a day, they rise in the east and set in the west. If you were to start watching a star in the east at the beginning of the night and keep observing that same star for hours, you will see the star's position move across the sky and eventually drop below the western horizon. There some stars that don't rise and set through the night though. The stars near the celestial pole move in circles around the pole. There is one star in the sky that doesn't appear to move at all, because it is located in line with the Earth's axis of rotation, or in other words, on the celestial pole. This star is Polaris, or more commonly known as the North Star. The south celestial pole currently lacks a star so there is no southern hemisphere counterpart. In reality, Polaris isn't perfectly on the celestial pole so even it moves in a very small circle too small to be seen with the naked eye.</span>

In comparing the advantages and disadvantages of nuclear energy with fossil fuels based electricity generation plants, do you th

Mashcka [7]

Answer:

Yes

Explanation:

Considering the following conditions;

1. Efficiency and Reliability

2. Availability of Resources

3. Emissions

4. Generating Electricity

Weighing nuclear energy and fossil fuels base on the above factors, nuclear energy represents a preferable option

1. Resources Availability

Uranium which is one of the most readily available source of energy is the major energy of nuclear energy and it's renewable and can be reprocessed.

While Fossil Fuels are non-renewable.

2. Emissions:

When electricity is being generated, nuclear energy is much more cleaner than Fossil energy.

3. Efficiency and Reliability:

As mentioned above, uranium powers the nuclear energy. Uranium atom can be splitted to form a nuclear energy, leading to a chain reaction called nuclear fission.

Organic reminants of plants and animals led to the formation of fossil fuels.

4. Generating Electricity

Both nuclear and fossil fuel power plants produce electricity the same way but the resources of fossil fuels is limited.

If the viscosity of slime is high, does that mean the bounciness of the slime also high?

Diano4ka-milaya [45]

Answer: No. Typically, the lower the viscosity is, the more it will bounce. If the viscosity of the slime is high, it will most likely just flatten out and not bounce at all.

Hope this helps!
