What is the 2nd harmonic also referred to? Second Harmonic Such positions are referred to as nodal positions or nodes. The lowest possible frequency at which a string could vibrate to form a standing wave pattern is known as the fundamental frequency or the first harmonic. Which generators have the lowest THD rating? The A-iPower […]
What does velocity relative to the ground mean?
What does velocity relative to the ground mean? The velocity of the object measured relative to the ground is called the ground speed. Again, this is a vector quantity. Airspeed is the vector difference between the ground speed and the wind speed. On a perfectly still day, the airspeed is equal to the ground speed. […]
What energy transformation takes place in a dry cell B electric fan?
What energy transformation takes place in a dry cell B electric fan? 1) in dry cell – chemical energy is converted to electrical energy. 2) In electric fan – electrical energy is converted to mechanical energy and wind energy . Which energy is converted in an electric cell? An electrical cell is an “electrical power […]
What are the 5 categories of adaptations?
What are the 5 categories of adaptations? The five categories of the adaptations are migration, hibernation, dormancy, camouflage, and estivation. The migration can be defined as the phenomenon of the movement of the animals from one region to another in order for their survival. What is an example of an amazing animal adaptation? Kangaroo rats […]
What is hydraulic principle?
What is hydraulic principle? The basic principle behind any hydraulic system is very simple – pressure applied anywhere to a body of fluid causes a force to be transmitted equally in all directions, with the force acting at right angles to any surface in contact with the fluid. This is known as Pascal’s Law. What […]
Is nitrogen-14 an isotope?
Is nitrogen-14 an isotope? Nitrogen-14 is one of two stable (non-radioactive) isotopes of the chemical element nitrogen, which makes about 99.636% of natural nitrogen. Nitrogen-14 is one of the very few stable nuclides with both an odd number of protons and of neutrons (seven each) and is the only one to make up a majority […]
How do you calculate area with pressure and force?
How do you calculate area with pressure and force? Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2. How is area related […]
Why centrifugal force is called pseudo-force?
Why centrifugal force is called pseudo-force? The centrifugal force is a pseudo-force because if the centripetal force ceased for an object in circular motion, the centrifugal force the body is “feeling” would instantly disappear, and the object would travel tangentially to its line of motion. Can centrifugal force overcome gravity? The centrifugal force is real […]
What is the structure and function of biomolecules?
What is the structure and function of biomolecules? Biomolecule, also called biological molecule, any of numerous substances that are produced by cells and living organisms. Biomolecules have a wide range of sizes and structures and perform a vast array of functions. The four major types of biomolecules are carbohydrates, lipids, nucleic acids, and proteins. What […]
What is a quasi experiment example?
What is a quasi experiment example? This is the most common type of quasi-experimental design. Example: Nonequivalent groups design You hypothesize that a new after-school program will lead to higher grades. You choose two similar groups of children who attend different schools, one of which implements the new program while the other does not. Why […]
