What is a metalloid that can be used as a semicondutors

Three resistance 4,4 and 6 ohms are joined in the series. the total resistance will be

The goal of this experiment was to answer the question, "how does diffraction occur? " suppose you formulated this alternate hypothesis: if the gap width is increased while keeping wavelength constant, then the observed diffraction will decrease because the less the ratio between wavelength and gap width is, the smaller the observed diffraction angle will be. to test this hypothesis, you would change the  gap widthdiffraction anglewavelength  and observe the  gap widthdiffraction anglewavelength  in the system. therefore, the independent variable would be the  gap widthdiffraction anglewavelength  and the dependent variable would be the  gap widthdiffraction anglewavelength.

If a substance cannot be physically separated into component parts, it is likely to be answers a mixture a pure substance an alloy a heterogeneous mixture
