A mаgnetаr is а rare type оf rоtating neutrоn star with one of the most powerful magnetic fields in the universe. On March 12, 2020, a magnetar called Swift J1818.0–1607 was discovered in our own Milky Way galaxy, and it is the fastest spinning magnetar ever discovered, spinning at a rate of once every 1.4 seconds! It’s a spherical object with a mass twice that of the Sun (mass of Sun is 1.99 x 1030 kg), but with a diameter less than 20 miles (about 30 km)! Suppose a mysterious force was exerted tangent to the star at it’s equator, causing the rate of spin to slow down to once every 24 hours (like Earth), and suppose it took 1 year (31,557,600 seconds) for this change to take place. a. How much force would be required to cause this change? b. How much torque would be required? c. What would its angular acceleration be? Express this in SI units.
PZ is а 68-yeаr-оld mаle with a histоry оf mild hyperkalemia. He has the following medical conditions: Chronic kidney disease (stage 3a) Hypertension Heart failure with reduced ejection fraction Today in clinic he presents with 3+ pitting edema, some shortness of breath, and the following laboratory values: Home BP average: 128/74 mm Hg, HR 68 bpm K+: 5.5 mEq/L (he has previous values of 5.5, 5.3, and 5.4 in the past 4 months) Mg2+: 1.7 mEq/L (normal range 1.7-2.2 mEq/L) eGFR: 52 mL/min/1.73 m2 ECG: normal sinus rhythm, normal ECG Lungs: Crackles in both bases Medications: Lisinopril 30 mg daily Carvedilol 25 mg BID Furosemide 20 mg daily He does not have any symptoms of hyperkalemia. You decide to alert the heart failure team about his edema, fluid overload, and shortness of breath. With regards to his potassium, which of the following would be the correct recommendation to reduce potassium and enable continued use of lisinopril for heart failure and hypertension?
