Final answer:
The correct scientific notation for the flow rate of steam is 3 x 10² kg/min and involves physics, specifically concepts in turbine engineering.
Step-by-step explanation:
The question refers to the flow rate of steam into a steam turbine. When it is stated that 'Three hundred kg/min of steam enters a steam turbine', the correct scientific notation for this number is 3 x 10² kg/min. This is because 300 can be expressed as 3 times 10 to the power of 2.
The discipline involved in dealing with units of measurement and the conversion to scientific notation is Physics, and this kind of problem is commonly encountered in the field of Turbine Engineering.
The question is asking for the amount of steam entering a steam turbine, which is 300 kg/min. This can be written as 3 x 10² kg/min, since 300 is equal to 3 times 10 raised to the power of 2.
So, the correct answer is option a) 3 x 10² kg/min.
