In the accompanying circuit, the battery and the ammeter have negligible resistance. The battery has an emf of 12 V. The light
bulb has a resistance of 0,5 ohm. Switch S is closed.
Calculate:
the effective resistance of the parallel resistors.
the reading on the ammeter.
the potential difference across the parallel resistors.
the strength of the current through the 3 ohm resistor.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5
