Imagine a circle with a diameter of 2km.if this represents an atom ,which answer would best represent the nucleus?choose the correct answer:a table tennis ball(diameter;2cm)atennis ball(diameter;7cm)avolley ball(diameter;20cm)a soccer ball(diameter;25cm)
a volley ball(diameter:20 cm)
To find the best representation of the nucleus of an atom with a diameter of 2 km, we need to compare the size of the nucleus with the given options.
Given options:
1. Table tennis ball (diameter: 2 cm)
2. Tennis ball (diameter: 7 cm)
3. Volleyball (diameter: 20 cm)
4. Soccer ball (diameter: 25 cm)
Note: All the given options are represented in centimeters.
To compare the sizes accurately, we need to convert the diameter of the atomic nucleus (2 km) to centimeters (cm).
1 km = 1000 meters
1 meter = 100 centimeters
Therefore, 2 km is equal to 2,000 meters, which is equal to 2,000,000 centimeters.
Now, let's compare the size of the atomic nucleus with the given options:
1. Table tennis ball (diameter: 2 cm)
The atomic nucleus is much larger than a table tennis ball, which has a diameter of only 2 cm. Therefore, it is not an accurate representation.
2. Tennis ball (diameter: 7 cm)
The atomic nucleus is much larger than a tennis ball, with a diameter of only 7 cm. Thus, it is not an accurate representation either.
3. Volleyball (diameter: 20 cm)
The atomic nucleus is still significantly larger than a volleyball, which has a diameter of 20 cm. Hence, it is not a precise representation.
4. Soccer ball (diameter: 25 cm)
The diameter of the atomic nucleus, which is 2 km or 2,000,000 cm, is relatively closer in size to a soccer ball's diameter of 25 cm. While still not an exact match, it is the best representation among the given options.
Therefore, the correct answer would be a soccer ball (diameter: 25 cm).
