Which element has the strongest coulombic attraction? Magnesium ion has a higher coulombic attraction compared to the coulombic attraction of Sodium. This is why Magnesium ion is more reactive than Sodium Ion. (Sodium has a +1 charge and Magnesium has a +2 charge. Magnesium has a higher coulombic attraction than sodium.) Which best describes the […]

What is the normal oxygen carrying capacity of hemoglobin? 1.34 ml How do you calculate oxygen content? The constant, 1.36, is the amount of oxygen (ml at 1 atmosphere) bound per gram of hemoglobin….Oxygen Content. CaO2 = 1.36 * Hgb * SaO2 + 0.0031 * PaO2 100 What is normal CaO2 content? Normal CaO2 ranges […]

Where is the strongest person in tug of war? Tips to win Tug of War Put the strongest person in the back so that he can use his strength the most and will have the least chance of slipping. Keep your arms and body almost straight as you lean backwards with your upper body while […]

What are the condition for system to be in mechanical equilibrium? For an object to be in equilibrium, it must be experiencing no acceleration. This means that both the net force and the net torque on the object must be zero. Here we will discuss the first condition, that of zero net force. What two […]

Why does my body lose heat so fast? The body loses heat through: Evaporation of water from your skin if it is wet (sweating). The body loses about 2% of its heat through air conduction. However, water causes more heat loss from the body than air does, so heat can be lost from the body […]

How far will a 50 watt FM transmitter reach? If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles. If 1 Million Watts of power is used, it is very likely that […]

What are the three difference between distance and displacement? Distance is a scalar quantity as it only depends upon the magnitude and not the direction. Displacement is a vector quantity as it depends upon both magnitude and direction. The distance can be measured along a non-straight path. Displacement can only be measured along a straight […]

What are the 7 functions of antibodies? Neutralization of Infectivity or Toxins. Phagocytosis. Complement-mediated lysis of pathogens or of infected cells. Antibody-dependent cellular cytotoxicity (ADCC) Tanscytosis, Mucosal Immunity and Neonatal Immunity. Types of Antibodies and their Major Functions. What are 5 types of antibodies? The 5 types – IgG, IgM, IgA, IgD, IgE – (isotypes) […]

Why is atmospheric pressure greatest at sea level? Most gas molecules in the atmosphere are pulled close to Earth’s surface by gravity, so gas particles are denser near the surface. With greater depth of the atmosphere, more air is pressing down from above. Therefore, air pressure is greatest at sea level and falls with increasing […]

Why is Aristotle a model of communication? The Aristotle’s communication model is a speaker centered model as the speaker has the most important role in it and is the only one active. It is the speaker’s role to deliver a speech to the audience. The role of the audience is passive, influenced by the speech. […]
