Mr. K., a 68‑year‑old man with a history of hypertension, hyperlipidemia, and coronary artery disease, visits the clinic reporting chest discomfort that occurs when he walks up his driveway or climbs stairs. He describes the pain as a “pressure” in the center of his chest that goes away within a few minutes after he rests.He states that the episodes have been happening for several months, and the chest discomfort is similar each time in location, intensity, and duration. Occasionally, he experiences mild shortness of breath during the episodes.He denies pain at rest, denies waking up with chest pain during the night, and has never noticed chest pain occurring unpredictably.Based on this clinical presentation, which characteristics describe chronic stable angina (CSA)? Select all that apply.

Two points, a and b, are located in the x-y plane, with coordinates given in meters (m), as shown in the figure. A uniform electric field of magnitude 5000 V/m is directed along the +x axis. A charged particle with charge Q = +[q] × 10-3 C is moved from point a to point b by an external force. The particle starts and ends at rest. Determine the change in the electric potential energy of the particle (in J). Note: the answer can be positive or negative.

An unknown charge Q is located at the origin. Two points, A and B, are shown in the x-y plane. The electric potential at point A is 200 V. What is the electric potential at point B = (0 m, [B] m) (in V)? Assume the electric potential at infinity is zero.
