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.

The speed you read on a speedometer is your instantaneous speed, which is the speed your vehicle is moving at a specific moment. This is usually measured in miles per hour (mph) or kilometers per hour (km/h), and it's calculated based on the rotation of your vehicle's wheels or drive shaft.
Explanation:
The speed you read on a speedometer is your instantaneous speed. This is the speed at which your vehicle is moving at a specific moment in time. On a standard speedometer, you'll see this represented as miles per hour (mph) or kilometers per hour (km/h), depending on your location and the standard measure of distance in your country.
The speedometer works by taking into account the rotation of the wheels or drive shaft and converting that rotational speed into a speed of linear motion.
For example, if you're driving and your speedometer says 60 mph, this means that at that particular moment, you are moving at a speed of 60 miles in one hour.

Answer:
Cooler
Explanation:
when you drive from city to farm the temperature of the farm is cooler than the temperature in the city.
this is because in city the population is very high as compare to the farms so, the activity of the city is also high which lead to increase the energy consumption of the area.
air pollutants, green house gases are also present more in the city which leads to increase the temperature of the city.
this effect is called urban heat island effect.

Answer:The correct answer is option C.
Explanation:
Nuclear decay is shown by those nucleus in which there is an imbalance between the number of neutrons and protons.
- If the ratio of neutrons to proton is 3:2 than it is a stable nucleus.
- If the ratio of neutrons to protons is not 3:2 than the nucleus will said to be unstable nucleus and it will undergo nuclear decay in order to gain stability.
Hence, the correct answer is option C.
