3. Four identical cells cach ofe. m.f. 1.5 volts with internal resistance are connected to form a banery of 6.0V. The battery is then joined in series with an ammeter of negligible resistance and fixed external resistance of 12 ohms. The ammeter then reads 0.3A. (a) Draw diagram of the circuit. (b) Calculate () the internal resistance of the battery, and (1) the value of the resistor which must be joined in parallel with the 12-ohm resistor to increase the ammeter reading to 0.5A​

What is the major limitation to the light microscope?

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
