What is Dimension and Unit? A dimension is a measure of a physical variable (without numerical values), while a unit is a way to assign a number or measurement to that dimension. For example, length is a dimension, but it is measured in units of feet (ft) or meters (m). the English Engineering System of […]
Can be broken down into two or more components?
Can be broken down into two or more components? Matter can be broken down into two categories: pure substances and mixtures. Pure substances are further broken down into elements and compounds. mixtures are phisically combined structures that can be seperated into their original components. A chemical substance is composed of one type of atom or […]
What is the most important muscle?
What is the most important muscle? The human heart is the most incredible muscle in the body, beating about 100,000 times to send 3,600 gallons of blood through 75,000 miles of blood vessels each day. Sure, skeletal muscles are vital to our ability to function, but the heart is truly a step above. What muscle […]
Why does a hollow sphere have more rotational kinetic energy?
Why does a hollow sphere have more rotational kinetic energy? Another hollow sphere of the same mass and radius is rotating about its axis through the center at the same rotation rate. Which sphere has a greater rotational kinetic energy? The hollow sphere, since the mass is distributed further away from the rotation axis. Does […]
What is the two main function of a diode?
What is the two main function of a diode? Main functions The most common function of a diode is to allow an electric current to pass in one direction (called the diode’s forward direction), while blocking it in the opposite direction (the reverse direction). As such, the diode can be viewed as an electronic version […]
Can sound waves bend?
Can sound waves bend? Sound waves do, indeed, bend. In an underwater thermal gradient the sonar waves can bend enough to create blind spots, so that you can not “see” a target that would ordinarily be well within sonar range. The other example is the difference in how well sound carries up/down wind. What is […]
Is VX and VY constant?
Is VX and VY constant? Here are some formulas that describe projectile motion: Thus the vertical velocity (Vy) is continually increasing. The horizontal velocity (Vx) remains constant and is equal to Vxo. If an object is pointed at an angle, the motion is essentially the same except that there is now an initial vertical velocity […]
How do electromagnetic fields affect the human body?
How do electromagnetic fields affect the human body? Low-frequency magnetic fields induce circulating currents within the human body. The strength of these currents depends on the intensity of the outside magnetic field. If sufficiently large, these currents could cause stimulation of nerves and muscles or affect other biological processes. How does frequency affect the human […]
What is LS coupling explain with example?
What is LS coupling explain with example? The energy levels which are characterised by certain values of L and S are called terms and the coupling of angular momenta of individual electrons to a resulting orbital angular momentum and spin is referred to as LS-coupling or Russell-Saunders coupling. Which is the selection role for LS […]
Does phagocytosis use clathrin?
Does phagocytosis use clathrin? Clathrin has been implicated as a necessary component of phagocytosis (15). Clathrin-coated pits are found in peritoneal macrophages (14, 16), and are located at surface adhesion sites (17) and phagosomes (18) in the macrophage. Does phagocytosis require ATP? Endocytosis methods require the direct use of ATP to fuel the transport of […]
