Two objects are moving towards each other with velocities $V_1$ and $V_2$ on a frictionless surface. They collide completely inelastically and move together after the collision with a velocity $V_3 = 17.6 \, m/s$ as shown below. If the ratio of the masses is $m_1/m_2 = 1.77$ and the angles are $\theta_1 = 38^\circ$ and $\theta_2 = 52^\circ$, what is the magnitude of $V_1$ in units of $m/s$? Express your answer using one decimal place.

You are working for a pharmaceutical company developing a promising new drug that targets a specific enzyme. The drug works really well when the target protein is isolated, but it doesn't work in intact cells that contain the target enzyme. The new drug has 2 amino groups with pKa's of 8.8 and 9.6. 1. You suspect the drug won't cross the hydrophobic plasma membrane at an extracellular pH of 7.8. Why do you think that? 2. You tell a chemist friend about your hypothesis, and they suggest that you modify the drug slightly so that the pKa's are altered in a way that makes the drug cross the membrane more readily. You think this is a great idea! How would the pKa's have to be changed in order to help it cross the membrane? Why is this?

Question 11 Suppose this battery and light bulb circuit failed to work: A B C D E F G H I J Using a voltmeter, a technician measures 0 volts between the points C and H. The result of this single measurement indicates which half of the circuit there is a definite problem in. What would you recommend as the next voltmeter measurement to take in troubleshooting the circuit, following the same "divide in half" strategy? Reveal answer
