Answer:
the length of pennies will be like the Proxima Centauri
Explanation:
50 pennies make the length of a meter, so :
50 pennies = 1 m
x = 1 km
x= (50 x 1000) = 50 000 pennies = 1 Km
Then if the Avogadro´s number is 6.022 x 1023 so:
50 000 pennies = 1 km
6.022 x 1023 pennies = x
x= (6.022 x 1023/ 50 000) = 1.2044 x 1019
This big number is closer to the 40 trillion km of the Proxima Centauri.
Hope this answer is useful.
According to NASA the only one of these that actually seems to be a real type of galaxy would be C. Barred Spiral Galaxy. I hope this helps :)
Answer:
true
Explanation:
A "population pyramid" shows a population distribution in reference to age which <em>typically looks like a pyramid if the population is increasing. </em>It also gives an information on the population's fertility or capability to reproduce and the country's economic situation.
The pyramid represents the<em> male population on the left side</em> and the <em>female population on the right side. </em>
The population pyramid may <em>"not always</em>" take the shape of the pyramid. An example of this is when the country is more developed. It takes the<em> shape of a kite. </em>Countries that are less-developed look more like a<em> pyramid in shape. </em>
