Explanation:
It is said that the bus moves with the speed of 72 km/hr.
It means that the bus covers 72 km in 1 hour.
so,
It covers 72 * 1000 m = 72000 m in one hour.
Hope it helps :)
They were able to find the orbit of a comet and predict the year of its return.
Answer:
Option A is the correct answer.
Explanation:
The instantaneous acceleration = Change in velocity in velocity/Time taken
The slope of the graph should give instantaneous acceleration.
Slope of a graph = Change in value of Y -axis / Change in values of X -axis
Comparing both the equations
Change in value of Y -axis = Change in velocity in velocity
Change in values of X -axis = Time taken
So velocity values should be on the Y axis and Time values should be on the X axis.
Option A is the correct answer.
