A point charge Q with a mass of m = [m] kg is submerged in a uniform electric field pointed vertically downward. Q = -[x] C. If the net force applied on the charge is zero, what is the magnitude of the electric field (unit in N/C)? Gravitational acceleration g = 9.8 m/s2. Note that magnitude is positive.
Read DetailsA client is admitted to the cardiac surgical intensive care unit after cardiac surgery. Four hours after admission to the surgical intensive care unit at 1600, the client has stable vital signs and normal arterial blood gases (ABGs), and is placed on a T-piece for ventilatory weaning. The following information pertains to the 1900 assessment. Assessments and Vital Signs Nursing Action Restless Performs complete assessment HR increased to 110 beats/min Suctions patient for pink, frothy secretions Respirations 36 breaths/min Obtains orders from provider for ABGs, electrolyte levels, and portable chest x-ray Blood pressure 156/98 mm Hg Sinus tachycardia 10 PVCs/min Elevated pulmonary artery pressure Loud crackles throughout New ABGs: pH: 7.28 PaCO2: 46 mm Hg Bicarbonate: 22 mEq/L PaO2: 58 mm Hg O2 saturation: 88% What interdisciplinary staff member does the nurse notify first to assist in the care of this client?
Read DetailsA point-charge, Q, is located at ([x0] m, 0) and has a value of -[Q]×10-7 C. Point A is situated at ([x1] m, 0). What is the magnitude of the electric field at point A? Express your answer in N/C. Note that magnitude is positive.
