Final answer:
The assertion regarding the straight-line depreciation method is false; it is indeed applicable when depreciation is based on time. In physics, the displacement versus time plot for constant acceleration is curved, whereas the displacement versus time squared is a straight line.
Step-by-step explanation:
The statement that the major limitation of the straight-line method is that it is inappropriate in situations in which depreciation is a function of time instead of activity is False. In reality, the straight-line method of depreciation is predicated on the notion that the value of an asset decreases uniformly over time, regardless of how much the asset is used. This is a function of time rather than activity. Therefore, the statement as presented contains a misunderstanding about the nature of straight-line depreciation.
However, addressing the physics questions provided:
- True or False: Consider an object moving with constant acceleration. The plot of displacement versus time for such motion is a curved line while the plot of displacement versus time squared is a straight line. The correct answer is True.
- True or False: The position vs time graph of an object that is speeding up is a straight line. The correct answer is False, as the graph would be curved, indicating increasing velocity.
When discussing the straight lines in graphs:
- A plot of activity as a function of time may result in a straight line if we plot In A versus t.
- The graph of acceleration versus time can be straight if the acceleration is constant, whereas displacement versus time would only be a straight line if the object moves at a constant velocity.
- The analytical method is generally more accurate than the graphical method, as graphical methods are often limited by the precision of drawing.
