Explanation

The maximum power transfer theorem states that maximum power is delivered to the load when the load resistance 𝑅𝐿 is equal to the source (or internal) resistance Rs of the power source.

Mathematically, this can be expressed as:

𝑅𝐿 =𝑅𝑠

When the load resistance matches the source resistance, the power transferred to the load is maximized.

Explanation

In longitudinal waves, the particles of the medium move back and forth in the same direction as the wave travels.

This results in compressions and rarefactions within the medium.

Explanation

Explanation

Metaphase, one of the most critical stages in mitosis

Chromosomes are most compact in metaphase

When the centromeres of the chromosomes of all cells are aligned with the equator of the mitotic spindle.

Chromosomes are most easily visualized at this stage,

So metaphase is especially useful in cytogenetics.
