Igneous rocks are conglomerates, predominantly composed of rounded
gravel
Explanation:
The statement that igneous rocks are conglomerate predominantly composed of rounded gravel is not correct. Igneous rocks are rocks formed from magma that cools and solidifies.
- Conglomerates are sedimentary rocks that are made of rounded clasts in a matrix.
- They differ from igneous rocks that crystallize from molten magma.
- Sedimentary rocks are usually derived from the process of weathering, erosion, transportation and deposition on the earth surface.
- Igneous rocks forms from crystallized magma which can be on the surface or deep within the crust.

I would say B but I have no clue
Nichrome wire. That's the stuff that toasters are made from. The resistance is pretty high, considering the diameter. 1 meter is at about the same guage as that listed below for copper is about 96 ohms.
Most of the time you are trying to use wire with the least resistance.
A meter of copper has a listed resistance of 0.024 ohms / meter. The wire is a 19 guage wire which makes it pretty thin.
===============
I'm not sure what you are asking. If want the resistance of something in terms of what would increase the resistance of the same material for both calculations then
Rule 1: It you decrease the wire diameter, you increase the resistance
Rule 2: If you increase the length of the wire, you increase the resistance.
Both rules assume you are using something like copper.
Explanation: White light is all colors of light in one, so when white light passes through a prism, the light gets refracted and breaks apart into all of the colors on the visible light spectrum.
