I didnt understand whther it is 11x103 or 11x10^3?? Well anyways i have solved it in both
Correct answer is A.
In a parallel circuit, the voltage is same across all the branches however the current in each branch is different and depends on the resistance of that branch. The higher the resistance, the lower the current.
In a series circuit, the voltage across each resistive element is different and depends on the resistance of that element. Higher the resistance, larger will be the voltage drop. However, the current throughout the series circuit is the same as there is only path in a series circuit.
Points to Remember:
1) In series circuit current remains the same and voltage varies
2) In parallel circuit voltage remains the same and current varies
To develop this problem we must apply the concepts related to the Ampere Law. The line integral of B.ds around any closed path is equal to the current permeability constant, this current for the particular case passes through the 'internal' surface delimited by the closed path.
Ampere laws is defined as,
The radius of the circle is r, so if
r < R
And there is no current inside so ,
Therefore the magnetic field inside the wall is Zero.
Answer:
Raising the highest point of the track to a higher point
Explanation:
When the rubber ball starts its motion, from the highest point of the track, it has only gravitational potential energy, given by:
where m is the mass of the ball, g is the gravitational acceleration and h is the height above the ground.
As the ball descends the track, this potential energy is partially converted into kinetic energy, given by:
(where m is the mass and v is the speed)
and partially lost as heat, due to the friction between the surface of the track.
As a consequence, the higher the initial height of the track (h in the formula), the greater will be the kinetic energy gained by the ball. A greater kinetic energy means a larger velocity, which also means that the ball will cover a longer distance before stopping.
