प्रश्न
Two students were asked to plot a distance-time graph for the motion described in Table A and Table B.
Table A
| Distance moved (m) | 0 | 10 | 20 | 30 | 40 | 50 |
| Time (minutes) | 0 | 2 | 4 | 6 | 8 | 10 |
Table B
| Distance moved (m) | 0 | 5 | 10 | 15 | 20 | 25 |
| Time (minutes) | 0 | 1 | 2 | 3 | 4 | 5 |
The graph given in Figure 13.2 is true for
पर्याय
both A and B.
A only
B only
neither A nor B
उत्तर
both A and B.
Explanation:
The distance-time graph for uniform motion shows a straight line. The slope is the same for both tables A and table B.
