Answer:
k = 0.1118 per min
Explanation:
Assume;
Initial number of bacteria = N0
Number of bacteria IN 'T' time = Nt
So,
![Nt=N0e^{-kt}\\\\in\ 6.2 min\\\\\\frac{N0}{2}= N0e^{-k(6.2)}\\\\ln\frac{1}{2} = -k[6.2]](https://tex.z-dn.net/?f=Nt%3DN0e%5E%7B-kt%7D%5C%5C%5C%5Cin%5C%206.2%20min%5C%5C%5C%5C%5C%5Cfrac%7BN0%7D%7B2%7D%3D%20N0e%5E%7B-k%286.2%29%7D%5C%5C%5C%5Cln%5Cfrac%7B1%7D%7B2%7D%20%3D%20-k%5B6.2%5D)
k = 0.1118 per min
Answer:
Yes
Explanation:
Yes steam power plant is heat engine.
As we know that a heat engine takes from source heat and produce some amount of work and reject the heat to the sink.
So the steam power plant fulfill the all requirement like it take heat from boiler and produce some amount work and then reject the heat by using condenser.So we can say that steam power plant is an example of heat engine.
Answer:
The growth rate is the dependent variable and that is option D
Explanation:
Since the study is based on the growth rate of babies which will be dependent on how the babies are fed - bottle fed and breast fed as pointed out in the question. This implies that Growth rate will be the dependent variable since it values will be dependent on the independent variable which are the bottle fed and breast fed, these may be manipulated or altered as the case may be.
