Answer:
Acceleration:
Final velocity:
Explanation:
To calculate the acceleration, you start from the formula:
Thus:
Now that you have the accelration, you can use the this formula to calculate the final speed:
Thus:
The direction of the magnetic force is to the right.
<h3>What is the magnetic field?</h3>
The magnetic field is the region in space where the influence of the magnet is felt. The magnetic force is always in the direction of the magnetic field.
We can see from the image, that the direction of the magnetic force is to the right.

<u>The electrical </u><u>power P</u><u> delivered to the </u><u>resistor </u><u>via the work done on the individual charges passing through it is</u><u> Power = VI</u>
What is power in physics and examples?
- Power is the rate at which work is done. The SI unit for power is the watt W, where 1 watt equals 1 joule/second (1W=1J/s).
- Because work is energy transfer, power is also the rate at which energy is expended.
- A 60-W light bulb, for example, expends 60 J of energy per second.
Let Length of wire L and register R .
Electric field of charge q
Force on charge q
F = E . q ⇒ V q /L
Work done in moving charge q distance L'
W = F L =
