A (shortening the conductor)
Since resistance = (resistivity × length) / cross sectional area, decreasing length decreases resistance

Ohm's 2nd Law:

Resistance = ro (coefficient) x Length/Area
$R = ro \times l \div a$

Shortening the Conductor: Length decrease, Area become greater than Length, Ro is a constant, so it doesn't change. Result: The Resistance will be lower.

Answer: A.

Why is the reflection of a wave at a free boundary different from reflection at a fixed boundary??

Gnoma [55]

Here is the main thing is medium. In the free boundary wave face the air medium, but in a fixed boundary wave face different medium. The change of medium effect on the change of the reflection of wave.

A train's velocity is slowly decreasing as it approaches a station. About 1 km before it reaches the station, several stowaways

Mars2501 [29]

Answer:

Increases

Explanation:

From Newton's second law:

F = ma

If F stays the same and m decreases, then a increases.

Therefore, the magnitude of the train's acceleration increases (the acceleration becomes more negative).
