Answer:
Explanation:
Magnitude of tension
= centripetal force
= m ω²R
= m (2π/T)² R , T is time period of revolution.
= .085 x (2 x 3.14 / .55)² x .84
= 9.3 N .
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.
Explanation:
Both graphs show plotted points forming a curved line. Curved lines have changing slope; they may start with a very small slope and begin curving sharply (either upwards or downwards) towards a large slope. In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity).

Answer:
Record your measured values of displacement and velocity for times t = 8.0 seconds and t = 10.0 seconds in the columns below.
Next, use the measured displacement and velocity values at t = 7.0 seconds and t = 9.0 seconds to interpolate the values of displacement and velocity at t = 8.0 seconds.
Use the following formula to interpolate and extrapolate. Remember, x and y here represent values on the x and y axes of the graph. The x values will really be time and the y values will be either displacement (x) or velocity (vx).
