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 […]
What are the 8 types of joints?
What are the 8 types of joints? Planar, hinge, pivot, condyloid, saddle, and ball-and-socket are all types of synovial joints. Is the wrist a gliding joint? Gliding joints occur between the surfaces of two flat bones that are held together by ligaments. Some of the bones in your wrists and ankles move by gliding against […]
What do you mean by hydraulic?
What do you mean by hydraulic? Hydraulics (from Greek: Υδραυλική) is a technology and applied science using engineering, chemistry, and other sciences involving the mechanical properties and use of liquids. In its fluid power applications, hydraulics is used for the generation, control, and transmission of power by the use of pressurized liquids. Where are hydraulic […]
When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be?
How does a person move forward during swimming?
How does a person move forward during swimming? A person applies force on the water in backward direction and water according to the third law of motion water apply an equal and opposite force in the forward direction which helps a person to swim. How do swimmers reduce drag? Here are ten good ways to […]
Is parsec is a unit of Time?
Is parsec is a unit of Time? Unfortunately, like the similarly misused ‘light-year’, the parsec is a unit of length, not of time. A parsec is equal to about 3.26 light-years or roughly 31 trillion kilometres (19 trillion miles). The unit has its origins in one of the first methods of determining the distance to […]
Why do plants look green in color 10?
Why do plants look green in color 10? Answer: The leaves of plants contain green pigments called chlorophyll which is necessary for photosynthesis. Plants reflect green light of sunlight, so they look green. Why are some plants not green in Colour? When leaves contain high concentration of anthocyanin pigments, the leaves appear red or purple […]
What is the electromagnetic spectrum used for?
What is the electromagnetic spectrum used for? Nearly all frequencies and wavelengths of electromagnetic radiation can be used for spectroscopy. Radio waves, infrared rays, visible light, ultraviolet rays, X-rays, and gamma rays are all types of electromagnetic radiation. Which color is the most refracted? violet light What is required for refraction? For refraction to occur […]
What is the significance of reference point for measuring distance?
What is the significance of reference point for measuring distance? A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. Objects that are fixed relative to Earth – such as a building, a […]
Can mitosis ever be used for human reproduction?
Can mitosis ever be used for human reproduction? In single-cell organisms, mitosis is the only form of cellular reproduction. One round of mitosis yields two genetically identical cells. This is classified as asexual reproduction because it does not require sex for the creation of new organisms. What cells does mitosis not occur in? You read […]
