What is a unit of force called? The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length — symbol m. The kilogram, unit of mass — symbol kg. The second, unit of time — symbol s. What is a unit of weight? The […]
What are the basic steps in transforming sound waves?
What are the basic steps in transforming sound waves? The outer ear collects sound waves, which are translated into mechanical waves by the middle ear and turned into waves in the inner ear. The auditory nerve then translate the energy into electrical waves and sends them to the brain, which perceives and interprets the sound. […]
What is the angle of incident ray?
What is the angle of incident ray? In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The angle of incidence at which light is first totally internally reflected is known as the […]
How does nuclear energy benefit the environment?
How does nuclear energy benefit the environment? Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels. […]
What is the main drawback of filament lamp?
What is the main drawback of filament lamp? The major disadvantage associated with filament bulbs is its cost. Though the initial costs are less, over the period, the current bills are going to be high since filament bulbs draw large units of power. This is because the filament bulbs spend nearly ninety percent of the […]
When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be?
How is stoichiometric coefficient calculated?
How is stoichiometric coefficient calculated? Almost all stoichiometric problems can be solved in just four simple steps: Balance the equation. Convert units of a given substance to moles. Using the mole ratio, calculate the moles of substance yielded by the reaction. Convert moles of wanted substance to desired units. What is the stoichiometric coefficient? The […]
Can WD 40 spontaneously combust?
Can WD 40 spontaneously combust? If the oil will cure and harden, then it is a fire hazard. WD40 won’t spontaneously combust. At what temperature does gasoline vapor ignite? 536°F. Is it safe to pressurize gasoline? 100 PSI isn’t exactly a small amount of pressure and in itself is rather dangerous. If the container bursts […]
What are 3 products of the light-dependent reactions?
What are 3 products of the light-dependent reactions? The products of the light-dependent reactions, ATP and NADPH, have lifespans in the range of millionths of seconds, whereas the products of the light-independent reactions (carbohydrates and other forms of reduced carbon) can survive for hundreds of millions of years. What is importance of light? It seems […]
What are the 3 magnetic materials?
What are the 3 magnetic materials? Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Does the human […]
