What is atomic radius?​
vfiekz [6]
The chemical element's atomic radius is measured by the size of its atoms, usually the medium or typical distance between the central nucleus and the surrounding electron shells. As the limit is not a well defined physical entity, different definitions of non-equivalent atomic radius exist.

Hope this helps!

What is the frequency,in Hz,of electromagnetic radiation that has a wavelength of 1.25m​
Kryger [21]

Answer:

f=2x10^8Hz

Explanation:

Hello!

In this case, given that frequency of the electromagnetic radiation showing off a wavelength of 1.25 m is computed by using the speed of light as shown below:

f=\frac{c}{\lambda }

We plug in the wavelength and speed of light to obtain:

f=\frac{3x10^8m/s}{1.25m } \\\\f=2x10^8Hz

Best regards!

What are the characteristics of an extrusive rock
olya-2409 [2.1K]

Extrusive Rocks. Igneous rocks which form by the crystallization of magma at the surface of the Earth are called extrusive rocks. They are characterized by fine-grained textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow.

how does resistance change with temperature? is there more resistance or less resistance at higher temperatures?
timofeeve [1]

The resistance has a linear relationship with temperature because it increases as temperatures increases.

<h3>What is temperature?</h3>

Temperature refers to the activity (motion or thermal energy) in the atoms that form molecules.

The resistance of an electric conductor increases as the temperature increases since the thermal energy of subatomic electrons also increases.

In conclusion, the resistance has a linear relationship with temperature because it increases as temperatures increases.
