You have a radioactive sample with a half-life of 1 hour. At t = 1 hour, a Geiger counter measures its radiation at 40 counts/minute. At t = 4 hours, it measures 5 counts/minute. Fill in the table for the activity at the unknown times (in counts/minute).
Time Geiger Counter Radiation Rate
0 hours
1 hour 40 counts/minute

4 hours 5 counts/minute

Is the alien theory a scientific claim? why or why not? just took the test it was , : " the alien theory is not a scientific claim because it is not based on valid data, there is no evidence to support it, and it does not come from a reliable source."
