Rolling without slipping means V=rw where w is angular velocity. So 4.0=0.1w
w=40rad/s
C) is correct
series circuit - in the same path : current flow on one path so they are equal on each component and equal to the source's. voltage on each components may be different.
parallel circuit - between same nodes : voltage of the components are equal and equal to the source's. current on each components may be different.
Search up criterion and look at the examples and then read it and then make it in your own words
The answer is A I believe. Hope this helps!
Answer:
Speed in km/hr will be 109.412 km/hr
Explanation:
We have given speed of the car on a highway = 68 mi/hr
We have to find the speed in km/hr
For this first we have to change mi to km
We know that 1 mile = 1.609 km
Speed is the ratio of distance and time
So 68 mi/hr
So the speed in km/hr will be 109.412 km /hr
