Answer:
The energy from water can be harnessed to be useful in a variety of different ways through water wheels or in hydroelectricity generating facilities. As water moves through some body, such as a river, its potential and kinetic energy vary. Additionally, if the area through which the water is moving changes size the pressure can also change. A device such as a turbine, can harness the kinetic and potential energy to be transformed into a type of useable energy, such as electricity

This is of course a very complex question that does not have a definitive answer, but 1850s would be a good decade to start counting as "Modern". This was a decade of the telegraph and Darwin's The Origin of Species.

Answer:
a.Costs initially go down and then go up.
Explanation:
The average total cost curve of an enterprise consists of the sum of the fixed cost curve and the variable cost curve. Fixed costs are those that cannot be eliminated in the short term, such as the utility bill. Varied costs are those that can be reduced if the company decreases the quantity produced. For example, inputs and labor.
Thus, initially the total cost curve tends to decrease as production increases, as fixed costs are slowly diluted as the production process advances. However, at some point this cost curve tends to increase, because if there is no economy of scale, marginal production will be decreasing, ie, after a certain point of production, each additional production will be more expensive (will require more variable costs ) and this will lead to an inflection in the average cost curve, which will increase further.
Answer: A) Self-regulation feedback
Explanation:
Self-regulation feedback is the response that is obtained by modifying and controlling the own-self according to the aim,learning and instruction. It helps in guiding the path and controlling the action for the feedback.
According to the situation in question, Mr.Nguyen has given self-regulating feedback for Shana as he wants her to check that document's heading is matching the standard of assignment by her own-self as she is already creating good slides.
Other options are incorrect because self feedback is self response ,process feedback is feedback that is response of a processing and task feedback is gained by performing the task.Thus, the correct option is option(A).
