Choose the correct answer:
1. A student records the distances covered by a train in successive equal intervals of \(10\ minutes\).
First \(10\ min\) - \(10\ km\)
Second \(10\ min\) - \(10\ km\)
Third \(10\ min\) - \(10\ km\)
Fourth \(10\ min\) - \(10\ km\)
What does the table indicate?
First \(10\ min\) - \(10\ km\)
Second \(10\ min\) - \(10\ km\)
Third \(10\ min\) - \(10\ km\)
Fourth \(10\ min\) - \(10\ km\)
What does the table indicate?
2. Four students observe objects moving along straight paths and make the following observations.
Student A: An object covers \(5\ m\), \(5\ m\), \(5\ m\) and \(5\ m\) in four equal intervals of time.
Student B: An object covers \(5\ m\), \(10\ m\), \(15\ m\) and \(20\ m\) in four equal intervals of time.
Student C: An object covers a total distance of \(40\ m\) in \(20\ minutes\).
Student D: An object moves along a straight line, but its speed keeps changing.
Which students have observations that can be used to identify uniform or non-uniform linear motion?
