Go through the distance-time graph of two cars A and B and choose the correct statement 

Go through the distance-time graph of two cars A and B and choose the correct statement  Correct Answer The speed of A is more than speed of B

Concept:

  • Distance: The path length between two points is called distance.
  • Speed (v): The rate of change in distance is called speed.
  • Distance vs time graph: The slope of the distance-time curve represents gives speed.

Slope (m) = tanθ

The slope of distance-time curve = speed (v) = tanθ  

Distance Time Graph

  • The distance-time graph represents distance v/s time. 
  • The straight line of the graph means the slope or rate of the graph is constant. 
  • The slope of the distance-time graph is speed, so a straight line means constant acceleration.

If it is not a straight line, the acceleration is non - uniform. 

Explanation:

  • The slope of the graph represents the speed of the graph. 
  • More is the slope, or the angle made by a graph with the time axis, more is the speed. 
  • From the given graph in the question, the slope of A is more than B.
  • So, the speed of A is more than the speed of B.

The question given below consists of a statement, followed by three arguments numbered I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments and which is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: State-run Energy Efficiency Services (EESL) has scrapped its second tender for procurement of 10,000 electric cars as the industry awaits clarification on specifications for chargers which will allow higher end, luxury automakers to come into the picture. This tender was floated in April and had been on hold after a preliminary pre-bid meeting. A similar tender was floated in August last year, and the rollout of 10,000 cars under the tender was expected to be completed by March 2019.  Why is EESL scraping the tender for procurement of 10,000 electric cars? Arguments: I. The share of luxury cars could go further up since it would be a good way of aggregating demand, Kumar said. This, however, strictly depends on the final order from DST. II. The tender had set aside 20% share of the total order for higher end and upgraded sedans category, which would allow foreign automakers like Nissan, Hyundai, Kia Motors to drive away with a fair share of the tender.  III. EESL said that the company has been awaiting clarification from the Department of Science & Technology (DST) to issue the standard norms for charging stations because of which the tender was first put on hold and now has been scrapped entirely.
