What is unpolarized light? A light wave that is vibrating in more than one plane is referred to as unpolarized light. Light emitted by the sun, by a lamp in the classroom, or by a candle flame is unpolarized light. Polarized light waves are light waves in which the vibrations occur in a single plane. […]

What is the typical size of magnetic domains?
What is the typical size of magnetic domains? 0.1 to 1 mm How do you align magnetic domains? Use the Magnet Position slider to move the magnet closer to the ferromagnetic material so that it interacts with the field lines.

What are the limits of mathematical models?
What are the limits of mathematical models? It is difficult to represent real-world systems in terms of mathematical relationships. Data are often unavailable or inaccurate. Combining the sub- system models to create the model is seldom simple. Assumptions and estimates must be made at almost every step of the process. What is the meaning of […]

What will eventually happen to the concentration of particles inside and outside the cell?
What will eventually happen to the concentration of particles inside and outside the cell? If the number of particles inside the cell is higher than the number of particles outside of the cell a hypotonic system has been established. Again the water molecules move more easily than the particles inside the cell. With the concentration […]
What is the normal oxygen consumption?
What is the normal oxygen consumption? The human lung consumes about 5-6 ml oxygen per minute at an esophageal temperature of 28 degrees C. Prebypass whole-body oxygen consumption measured at nearly normothermic conditions was 198 +/- 28 ml/min. Mean lung and whole-body respiratory quotients were similar (0.84 and 0.77, respectively). What is the rate of […]
