The current initially through the fingers is : 1.5 * 10⁻⁵ amp
The current when the resistance between them drops is : 3 * 10⁻⁵ amp
<u>Given data : </u>
Voltage ( V ) = 6 V
Initial resistance ( r ) = 400,000 ohms
Final resistance ( R ) = 200,000 ohms
<h3>Determine The Current </h3>
A) initially through fingers
I = V / r
= 6 V / 400,000
= 1.5 * 10⁻⁵ amp
B) when the resistance between them drops
I = V / R
= 6 V / 200000
= 3 * 10⁻⁵ amp
Hence we can conclude that The current initially through the fingers is : 1.5 * 10⁻⁵ amp and The current when the resistance between them drops is : 3 * 10⁻⁵ amp

The amount of work done by the student in carrying the backpack is 30.6 J
<h3>Definition of workdone </h3>
Workdone is defined as the product of force and distance moved in the direction of the force.
Work done (Wd) = Force (F) × distance (d)
Wd = Fd
Also,
Force (F) = mass (m) × acceleration (a)
F = ma
Therefore,
Wd = (ma) × d
With the above formula, we can obtain the work done by the student.
<h3>How to determine the Workdone </h3>
From the question given above, the following data were obtained:
- Mass (m) = 12 Kg
- Acceleration (a) = 0.51 m/s²
- Distance (d) = 5 m
- Workdone (Wd) =?
Wd = (ma) × d
Wd = 12 × 0.51 × 5
Wd = 30.6 J

<span>I am pretty sure the correct answer is C.
It makes the most sense.
Please correct me if I'm wrong.</span>
Answer:
how the areas are at
Explanation:
The tilt of the Earth's AXIS is the most important reason why seasons occur... The area depends why there's a certain differnt season on differnt areas , its because one area is closet to the sun which mostky they get summer full time (like a normal year), but Alaska,it just winter , the reason why Alaska is just cold because its not close to the sun.
