5. [0/1 Points] DETAILS MY NOTES OSCOLPHYS2016 13.2.WA.018. PREVIOUS ANSWERS ASK YOUR TEACHER PRACTICE ANOTHER Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 24.5-L capacity when at 11.0°C. What volume of radiator fluid will overflow when the radiator and fluid reach their 95.0°C operating temperature, given the fluid's volume coefficient of expansion is $400 \times 10^{-6}/^\circ C$ and that of copper is $51 \times 10^{-6}/^\circ C$. Note that most car radiators have operating temperatures of greater than 95.0°C. 0.00000718 X Note that the radiator will also expand due to the temperature increase.

How is Einstein's famous equation, E = mc2, important in understanding the Sun? The Sun generates its energy by converting 4 million tons of mass to energy each second.The Sun's surface temperature is about 6,000° Celsius.The Sun has a magnetic field strong enough to influence the atmospheres of the planets.This equation represents how difficult science is, so understanding the Sun is difficult as well.

4. Consider a piece of silicon A is doped with both donor and acceptor impurities as: $N_D = 2.5 \times 10^{15} \text{cm}^{-3}$ and $N_A = 1.3 \times 10^{13} \text{cm}^{-3}$. Another piece of silicon B is doped with only donors $N_D = 1.2 \times 10^{13} \text{cm}^{-3}$. Assuming complete ionization of impurities and the intrinsic carrier concentration $n_i = 10^{10} \text{cm}^{-3}$. Which of the following statement is true? (4 points) a) Electron concentration in sample A > sample B b) Electron concentration in sample A < sample B c) Electron concentration in sample A is approximately equal to sample B d) Additional information is needed. 5. Two semiconductor materials have exactly the same properties except that material A has a band gap value of 1.0 eV and material B has a band gap value of 1.2 eV. Determine the ratio of the intrinsic carrier concentration $n_i$ of material A to that of material B at room temperature. (4 points) a) 32.4 b) 2191.4 c) 46.8 d) 75.3 6. What is the charge state of an occupied donor (i.e., a donor atom has been occupied by an electron) and what is the charge state of an unoccupied acceptor (i.e., an acceptor atom has not been occupied by an electron)?
