i would say, are sour and corrode metals
Answer:
Population 1 indicates growth while Population 2 indicates a declining population
Explanation:
Here, using the given rate of change of the population, we want to determine which of the two is growing and which is declining
From the rate of change of both, we can determine this. Looking at the differential equation for the first one, we can see that it is of positive value. Looking at the differential equation for the second one. we can see it is of negative value
While a positive change rate indicates growth, a negative change rate will indicate otherwise
Hence, we can conclude that the one with a negative rate change will indicate a declining population
Answer:
Since the bar cannot translate, linear momentum is not conserved
Explanation:
By conservation of the angular momentum:
Lo = Lf
where
; 
; d=1.6m; L=3m; 
; 
; 
Solving for 
:
Replacing the values we get:
Since the bar can only rotate (it canno translate), only angular momentum is conserved.
