Step 1: From the given acceleration-time graph, we observe that the acceleration is constant.
Step 2: The velocity-time graph is the integral of the acceleration-time graph with respect to time. Since acceleration is constant, the velocity increases linearly with time.
Step 3: With initial velocity zero, the velocity-time graph is a straight line starting at the origin and increasing with time.
The motion of an airplane is represented by the velocity-time graph as shown below. The distance covered by the airplane in the first 30.5 seconds is km.
A quantity \( X \) is given by: \[ X = \frac{\epsilon_0 L \Delta V}{\Delta t} \] where:
- \( \epsilon_0 \) is the permittivity of free space,
- \( L \) is the length,
- \( \Delta V \) is the potential difference,
- \( \Delta t \) is the time interval.
The dimension of \( X \) is the same as that of:
