D. The force and displacement are in the same direction

Answer:

500 m

Explanation:

The size of a nucleus is about

Instead, the size of the electron cloud extends at the order of

This means that the ratio between the size of the electron cloud and the size of the nucleus is about

So, the electron cloud is about 10,000 bigger than the nucleus of the atom.

Here we want to build a scale-model atom, in which the nucleus is the size of a tennis ball, so a size of approximately

Therefore, since the proportions must be respected, the electron clouds must be 10,000 bigger, so its size in this model would be:

So, the size of the electron cloud would be 500 m.

Final answer:

The cloud of electrons in a scale-model atom would extend about 100 meters.

Explanation:

The nucleus is a central, positively charged region within an atom. It contains protons, which have a positive electric charge, and neutrons, which are electrically neutral. Nuclei make up the majority of an atom's mass and are held together by the strong nuclear force, while electrons orbit the nucleus in electron shells.

In a scale-model atom where the nucleus is the size of a tennis ball, the cloud of electrons would extend about 100 meters. This can be calculated by comparing the size of the nucleus to the actual size of an atom. The diameter of a tennis ball is approximately 6.7 cm, while the diameter of an atom is on the order of 0.1 nm. By scaling up, we find that the electron cloud would extend around 100 meters.

Answer;

-Interruption of natural biome processes

Explanation;

-Human beings have continuously continued with interference of different biomes and thus bringing various modifications to these biomes. Human activities often affect ecosystems in negative ways because human systems are not closed loop systems. For example; human waste enters other natural ecosystems, where it can cause them to become unbalanced

-If efforts are not enhanced in conserving the natural world, we shall continue experiencing deteriorating weather factors like the global warming. Failure to conserve our biosphere will ultimately hurt the human race, together with organisms in various biomes.

Final answer:

Human impacts on biomes include changes in biodiversity, alterations in ecosystem structure, and climate change. These impacts stem from human activities like deforestation, mining, pollution and the emission of greenhouse gases.

Explanation:

Human impacts on biomes are best characterized by changes in biodiversity, alterations in ecosystem structure, and climate change. The significant increase in human population and activities such as deforestation, mining, and pollution lead to biodiversity loss and habitat destruction. These activities collectively trigger alterations in the ecosystem structure. Additionally, human-induced emissions of greenhouse gases contribute to global climate change, which further disturbs the biomes - the various life zones on Earth. Therefore, the major human impacts on biomes include changes in biodiversity, ecosystem structure alterations, and climate change.
