Time left 1:52:26 How many atoms are there in 7.0 mol of the organic molecule with molecular formula, $C_5H_{10}O_2$ (Hint: Take care. Many students trip up on this question because they calculate the number of molecules. But the question is asking for the number of atoms, NOT the number of molecules!) (Note the choices below may be given in 'exponential format, e.g. 1200000 = $1.2x10^6$ would be displayed as 1.2e6) ○ 7.2e25 Ο 119 ○ 1.0e25 O 4.2e24 O 1.2e-23 Ο 7.0 Ο 17 Next page

An inductor with inductance L and a resistor with resistance R are wired in series to an ideal battery with emf \mathcal{E}. A switch in the circuit is closed at time t = 0, at which time the current is zero. A long time after the switch is thrown the potential differences across the inductor and resistor are: ? 0, \mathcal{E} ? \mathcal{E}, 0 ? \mathcal{E}/2, \mathcal{E}/2 ? (L/R)\mathcal{E}, (R/L)\mathcal{E} ? unknown since the rate of change of the current is not given
