What are advantages of modified Rankine Cycle? It is released at a higher pressure and then there is a pressure drop at constant volume down to condenser pressure. This early release causes reduction in efficiency because the work for the cycle is reduced while the heat supplied per cycle remains the same. This cycle is […]
What are the 2 types of mass?
What are the 2 types of mass? In classical mechanics, there are three types of mass or properties called mass: Inertial mass; passive gravitational mass; and active gravitational mass. Where do we use mass in everyday life? Another example of everyday use is mass producing a recipe. Say you are making an extremely large cake […]
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 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 […]
When an electron makes a transition from the N 4 to the N 2 then emitted line spectrum will be?
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 […]
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 […]
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 […]
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 […]
What is shear strength test?
What is shear strength test? Shear strength measures a material’s ability to resist forces that cause the material to slide against itself. A universal test machine is used to apply the tensile or compressive load to determine the overall strength of the adhesive once the samples are pulled or pushed apart. … Why is shear […]
