19) The resistance of $R_1$ is $5\Omega$ and $R_2$ is $10\Omega R_2$ is made of a nichrome wire (resistivity of $1.5\times 10^{\circ }\Omega \mathrm{m}$ ) that is $8\mathrm{m}$ long and has a cross-sectional area of $6\times 10^7{\mathrm{m}}^2$. The voltage of the battery is $12\mathrm{V}$. a) What is the resistance of the wire that makes $R$ ?? b) Fill out a VIRP chart c) How many electrons go through the main wire (wire connected to the battery) each minute? d) Write Kirchhoff's Current Law for this circult e) Write Kirchhoff's Voltage Law for each loop f) What is the electromotive force of the battery if the internal resistance is: $2\Omega$ ? 9) The 2nd resistor is a speaker that is giving off a frequency of $256\mathrm{Hz}$ in a room that is $18.\mathrm{C}$ and has an air density of $1.29\mathrm{kg}/\mathrm{m}$. What is the sound intensity at a point that is 6 meters away from the speaker? h) What is the decibel level at that point? (i) What is the speed of sound in that room? 1) If you are running towards the speaker at a speed of $10\mathrm{m}/\mathrm{s}$, what is the apparent frequency that you hear? k) What is the Bulk modulus in that room?
