4. The pKa values of the ortho, para, and meta substituted benzoic acids are shown below. Use words and drawings to explain these relative acidities. (7 points) HO. 0 HO0 HOO NH2 NH2 NH2 pka = 4.89 pka = 4.95 pka = 4.73
Can you please explain Q7.2? I have the answers here, but I'm having trouble understanding what is happening to the circuit when the switch is at b. How is it possible to draw a circuit this way when there is no return path? (please see my hand drawing). 7.2 At 0, the switch in the circuit shown moves instantaneously from position a to position b a) Calculate vo for t 0. b) What percentage of the initial energy stored in...
Please help with this physics 009 question! I'm especially having trouble figuring out how to calculate the product of the two vectors! And calculating the angle between them! Vector ?⃗ has a magnitude of 16.6 and is at an angle of 30.5∘ counterclockwise from the +?‑axis. Vector ?⃗ has a magnitude of 29.1 and is −50.3∘ from the +?‑axis. Resolve ?⃗ and ?⃗ into components, and express in ??? unit vector form, ?⃗=???+??? ?⃗=???+??? Vector A has a magnitude of...
I am having trouble with answering part 2 of these ray tracing, can you please help me?

Hi, I'm having trouble understanding and answering this question and I do not have any solutions to go off by. Please help? Integration of Metabolism/Signalling Question 3 Compare the metabolism of a 100 m sprinter, a 42.2 km marathon runner and a combined 226.3 km ironman triathlete. Your job is to determine the value or description of each of the parameters labelled 'A' to 'J'in Table I below, find its code number in Table II (Code Numbers for Question 3)...
I have two questions I'm having trouble understanding. I greatly appreciate any help you all can give me! I'm not great at physics so the more details the better. THANKS!!! In the RC circuit of Figure WG32.6, the emf of the AC source is given by 'E = Emax sin ω| t. The emf amplitude is Emax = 10 V, and the angular frequency is ω,-100 s-1 when the angular frequency is changed to a new value ω2, the time...
