If 8 amperes of current is pushed through a 2 2 resistor by a battery. What is the voltage? (Formula V=I x R)
140 Volts
16 Volts
300 Volts
8 Volts

Adozen is 1221/12 = 1.751.75 x 12 = 21therefore, 1.75 is the answer.

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Use a magnet to separate iron, evaporate water, i'm not sure how to separate the other two i'm sorry but good luck
