How does natural selection cause a population to change over time
Andreyy89
Learning evolution huh? Good question there. Natural selection alters the gene frequency in a gene pool, changing the population.
Natural selection tends to promote adaptation by maintaining favorable adaptations in a constant environment (stabilizing selection) or improving adaptation in a direction appropriate to environmental changes (directional selection).

A circuit has an impedance of 5 ohms and a voltage of 100 volts. What is the current flow?
Ket [755]

A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.

The expression of an electronic component, circuit, or system's resistance to alternating and/or direct electric current is called impedance, indicated by the letter Z. Resistance and reactance are two distinct scalar (one-dimensional) phenomena that combine to form impedance, a vector (two-dimensional) variable.

Z^{} = \frac{V}{I}

(for a pure resistor where Z=R,preserving the form of the DC Ohm's law).

I=\frac{V}{Z}

I = \frac{100}{5}

I = 20 A

Therefore, A circuit with an impedance of 5 ohms and a voltage of 100 volts has a current flow of 20 A.
