Chapter 16 Notes The heart lies in the mediastinum and is surrounded by a doubled layered membrane called the pericardium. The outer most layer of the pericardium is called the fibrous pericardium‚ which anchors the heart to surrounding structures. The inner layer is called the serous pericardium and is composed of two layers. The outer portion is called the parietal pericardium‚ the inner portion is called the visceral pericardium (epicardium). Epicardium- outer most layer of the heart wall

most any material. GOOD LUCK! Abstract: In this lab we determined the freezing point‚ and Kf‚ of pure 2‚4‚dichloralbenzne as well as a 2‚4‚dichloralbenzne/biphenyl solution. We used this information to determine the molar mass of an unknown (#24) by the 3rd step in the experiment which was a 2‚4‚dichloralbenzne/unknown solution. All of the above we charted the time temperature for the later calculations. I. Introduction A. Background This experiment shows how one determines the temperature-composition

CHAPTER 4 Objectives: 1. Define consciousness.--------- 2. Appreciate the role of the circadian rhythm. 3. Describe the stages (5) of sleep including the sequence of the stages. The development of the electroencephalograph led to dramatic increases in what is known about sleep. When electrodes are attached to the face and scalp of sleepers‚ different patterns are produced on the graphic record called the electroencephalogram or EEG. The patterns vary in frequency and amplitude of the waves

Assignment Week 4 Chapter 11 20. A parallel RL circuit has values of IL = 240 mA and IR = 180 mA. Calculate the magnitude and phase angle of the circuit current. It=√ IL^2 + IR^2= √ 240mA^2 + 180mA^2= 0.3 x 10^-3= 300mA θ= tan^-1(-IL/IR)= (-240mA/180mA)= -53° 300mA∟-53° 22. Calculate the total impedance for the circuit shown in Figure 11.38b. It= √IL^2 + IR^2= √800mA^2 + 120mA^2= 0.808949 x 10^-3= 808.95mA Zt= Vs/It= 120V/808.95mA = 148Ω θ= tan^-1(-IL/IR)= (-800mA/120mA)= -81.5= 82° 148∟82° 24
