What are the conditions to be satisfied to avoid interference? To set up a stable and clear interference pattern, two conditions must be met: The sources of the waves must be coherent, which means they emit identical waves with a constant phase difference. The waves should be monochromatic – they should be of a single […]
What is the function of medulla in kidney?
What is the function of medulla in kidney? The main function of the medulla is to regulate concentration of the urine. The urine flows from the collecting ducts into the renal calyces and pelvis, which undergoes unidirectional peristaltic movements to allow drainage of the urine into the downstream ureter and bladder. What are the three […]
What lowers biotic potential?
What lowers biotic potential? These factors include unfavourable climatic conditions; lack of space, light, or a suitable substrate; deficiencies of necessary chemical compounds or minerals; and the inhibiting effects of predators, parasites, disease organisms, or unfavourable genetic changes. How do you get biotic potential? Biotic potential is the ability of a population of living species […]
Is black light infrared?
Is black light infrared? NOUN: Invisible ultraviolet or infrared radiation. Black light causes fluorescent materials to emit visible light and is used to take pictures in the dark. Can you cure gel nails without UV light? While you will be able to apply gel nail polish without a UV light, the other “processes” of drying […]
How can the black coating on the surface of copper be turned reddish brown?
How can the black coating on the surface of copper be turned reddish brown? Answer. when hydrogen gas is passed over a black coloured substance ‘X’, the coating of on its surface turns brown. Copper metal is reddish brown in colour and when burnt it air, it turns black due to the formation of copper […]
What is the path of charged particle when it moves at an angle of 180º with magnetic field?
What is the path of charged particle when it moves at an angle of 180º with magnetic field? The path of a charged particle in a uniform magnetic field depends on the angle θ between velocity vector and magnetic field, When θis0∘or180∘,Fm=0 hence path of a charged particle will be linear. When θ=90∘, the magnetic […]
How much work is done on a 300 Newton suitcase to lift it 0.50 meter?
How much work is done on a 300 Newton suitcase to lift it 0.50 meter? 1 Answer. Work done is force multiplied by distance, Hence work done is 300×0.50=150 joules. What is the principle of work and energy? The principle of work and kinetic energy (also known as the work-energy theorem) states that the work […]
Why is premium gas so expensive 2020?
Why is premium gas so expensive 2020? AAA said the demand for premium gas is due to more car owners “treating themselves” as pump prices drop. But another factor driving demand is that more stringent fuel-economy standards have put downsized and turbocharged engines in more and more new cars. Is premium gas a waste of […]
How do you know if a light is continuous or discrete?
How do you know if a light is continuous or discrete? Typically one can observe two distinctive classes of spectra: continous and discrete. For a continuous spectrum, the light is composed of a wide, continuous range of colors (energies). With discrete spectra, one sees only bright or dark lines at very distinct and sharply-defined colors […]
What are the key concepts of Vygotsky theory?
What are the key concepts of Vygotsky theory? Vygotsky’s Cognitive Development Theory postulates that social interaction is fundamental to cognitive development. Vygotsky’s theory is comprised of concepts such as culture-specific tools, language and thought interdependence, and the Zone of Proximal Development. What is the importance of scaffolding? Instructional scaffolding is a process through which a […]
