Answer:
63.8 V
Explanation:
We are given that





Potential difference,V=140 V
We know that

According to question

In series





Potential across 1.2 square cm=
Hence, the voltage across the 1.2 square cm wire=63.8 V
Her average speed was 55MPH. Hope this helps!
Answer:
Option B
Explanation:
The instantaneous velocity = Change in position/Time taken
The slope of the graph should give instantaneous velocity.
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 position
Change in values of X -axis = Time taken
So position values should be on the Y axis and Time values should be on the X axis.
Distance on the y-axis and time on the x-axis.
So, option B is the correct answer.
I believe that air, bicycles, people, clothes and trees are matter however sound waves and sunlight are not. :)
