Answer:
21 minutes or 0.35 hours
Explanation:
The formula for exponential population growth is
![A = A_0* e^{kt}\\](https://tex.z-dn.net/?f=A%20%3D%20A_0%2A%20e%5E%7Bkt%7D%5C%5C)
where
initial population of E.coli i.e 100
k is the rate of population growth i.e 2 as the population doubles
t is the time period i.e 20 minutes
Substituting the given values in above equation, we get -
![A = 100 * e^{2 * \frac{20}{60} }\\\\A = 195](https://tex.z-dn.net/?f=A%20%3D%20100%20%2A%20e%5E%7B2%20%2A%20%5Cfrac%7B20%7D%7B60%7D%20%7D%5C%5C%5C%5CA%20%3D%20195)
Generation time

or 0.35 hours
Answer:
How are radio telescopes used to explore space?
Since the 1930s, when the first radio signals from space were detected by Karl Jansky, astronomers have used radio telescopes to explore the Universe by detecting radio waves emitted by a wide range of objects.
