7. (10 pts) You wish to chill some freshly brewed tea ($T = 95^\circ C$) to a temperature where you can drink it without burning your tongue, using the minimum amount of ice to avid watering it down too much. What amount of ice should you add to 2.0 kg of tea to cool it down to $75^\circ C$? The ice is initially at a temperature of $-5^\circ C$ and is in an insulated container, and you can assume tea has the same specific heat as water. Relevant heat capacities: specific heat of water: $4180 \frac{J}{kg \cdot K}$, specific heat of ice: $2090 \frac{J}{kg \cdot ^\circ C}$, heat of fusion: $3.34 \times 10^5 J/kg$

A sphere of radius R = 0.255 m and uniform charge density 151 nC/m³ lies at the center of a spherical, conducting shell of inner and outer radii 3.50R and 4.00 R, respectively. The conducting shell carries a total charge of Q = -90.5 nC, Determine the magnitude E(r) of the electric field at the given radial distances $r$ from the center of the charge distribution. E(0.460R) = 588.6 N/C Incorrect E(3.90R) = 0 N/C E(3.35R) = 114 N/C Incorrect E(5.90R) = 0 N/C Incorrect

Q2) Note: The concentration of Na$^+$, Cl$^-$ and Ca$^{2+}$ are high in the exoplasm. In contrast the concentration of K$^+$ is high in the cytoplasm of the neuron. The worm C. elegans moves towards or away from an odor using the neuronal circuitry shown below. ODOR Neuron 1 Neuron 3 Neuron 2 Moves towards Moves odor away from odor Optogenetics experiments can be applied to the worm to investigate the roles of specific neurons in odor sensing. For a) and b) below, choose from the following options: worm moves towards the odor/ worm moves away from the odor/ worm is unresponsive to the odor and explain why you selected the response. a) The light-activated channel rhodopsin (ChR1) opens in response to blue light and allows passage of Na$^+$ ions across the membrane. You construct a C. elegans where the ChR1 channel is expressed exclusively in Neuron 2. Then you expose the worm to an odor (ethanol). What response would you predict on stimulation with blue light and why? b) The light-activated Halorhodopsin channel (NpHR) opens in response to yellow light and allows passage of Cl$^-$ ions across the membrane. You construct a C. elegans where the NpHR is exclusively expressed in Neuron 1. Then you expose the worm to an odor (ethanol). What response would you predict on stimulation with yellow light and why?
