Final answer:
In physics, the relation between motion graphs and positions is crucial for understanding concepts such as acceleration and displacement. A position vs time graph for an object speeding up will be curved, not straight, electric-field lines from a positive charge point outward, and the amplitudes of co-linear waves can add up.
Step-by-step explanation:
The statement "A spotting of 'LINE' is a round that impacts on line with the adjusting point as seen by the observer (on the observer-target line)" is related to observations often made in the context of ballistics or surveying, which are grounded in physics principles. When dealing with graphs and motions in physics, it's important to understand the relation between them:
- Position vs time graph: A position vs time graph for an object that is speeding up will not show a straight line; it will be a curved line because the speed (slope of the line) is changing. Therefore, the answer would be False.
- Electric-field lines from a positive point charge indeed spread out radially and point outward, so this is True.
- For waves, the amplitude of one wave is affected by the amplitude of another wave when they interfere with each other, which does not require precise alignment, making this statement False.
- It is True that a vector can be represented as a right angle triangle with its x and y components forming the perpendicular sides.
- Furthermore, when waves are co-linear (propagating in the same direction), their amplitudes can add up, confirming that the statement is True.
With respect to displacement and motion:
- The plot of displacement vs time for an object moving with constant acceleration is indeed a curved line, while the plot of displacement vs time squared for the same motion is a straight line, because the relationship between displacement and time squared in uniformly accelerated motion is linear, so this statement is True.
