Answer;
- the direction the wire moves in
- the direction of the magnetic field
Explanation;
The direction of an electric current is also the direction in which a positive charge would move.
The direction of flow of electric current in a current carrying conductor such as a wire depends on a number of factors. These factors includes; the direction the wire moves in; that is current will flow towards the direction of a given wire or conductor.\
Secondly, the direction of magnetic field determines the direction of flow of electric current; this can be explained by the idea of induced current; the direction of induced current depends on the direction of magnetic field according the Fleming,s right hand rule.
Just divide the two numbers
Answer:
vp = 0.94 m/s
Explanation
Formula
Vp = position/ time
position: Initial position - Final position
Position = 25 m - (-7 m) = 25 m + 7 m = 32 m
Then
Vp = 32 m / 34 seconds
Vp = 0.94 m/s
1. Changing voltage increases the current.
2. Adding more lightbulbs increase the resistance and the light bulbs become dimmer as the current has to be shared.
3. Yes its constant.
