Answer:
The electric charge passes is 15.2 C.
Explanation:
The electric current is drawn from a battery = 16 A
The diameter of copper wire is = 5 mm
The length of copper wire is = 1.52 m
Running time of starter motor before the start of car engine = 0.95 s
Therefore, the current 16 A passes through the copper wire for 0.95 seconds.
The calculation of electric charge passes:
<em>Average velocity is defined as the ratio of change in position to the time taken for that change. </em>
Answer: <em>True</em>
Explanation:
Velocity is obtained by dividing the displacement of an object by time interval. Displacement is a vector quantity which is defined as the shortest distance between initial and final point of an object.
In other words, displacement is the change in position of an object. A position-time graph can be plotted to find the average velocity of an object graphically. The average velocity can be obtained by calculating the slope of the position-time graph.
While average velocity deals with velocity over a particular time interval, instantaneous velocity gives the velocity of an object at a particular point of time or instant.
