Answer:
Explanation:
Radius of the ball is
Initial speed of the ball is
Initial angular speed of the ball is
Coefficient of kinetic friction between the ball and the lane
is
Due to the presence of frictional force, ball moves with
decreasing velocity.
(a)
velocity in terms of is
(b)
Ball's linear acceleration is given by
(c)
During sliding, ball's angular acceleration is calculated as
(d)
The time for which the ball slides is calculated from the
equation of motion is
(e)
Distance traveled by the ball is
(for)
The speed of the ball when smooth rolling begins is
Hi, this is a question about an experiment, video or lesson you did in class so just look at what you predicted would happen and if it happen then your answer is yes,<span> the aluminum foil and the versoriums </span>did react the way I predicted, but if not then just say no it did not and say how you can improve your predictions
I feel like my answer is wrong but I think it B) false or C) true
The resistance of the cylindrical wire is .
Here is the resistance, is the length of the wire and is the area of
cross section. Since the wire is cylindrical .
Comparing two wires,
Dividing the above 2 equations,
Since
The above ratio is
We also have,
The current through the Silver wire will be 4.23 times the current through the original wire.
