Fluid speed would differ depending on exactly where inside the pipe you’re considering (generally slowest near the wall, fastest near the center) and whether the fluid is a gas or liquid (the former could be subject to significant changes in density under certain conditions). But as a general rule,Read more

Forest in Nepal
Sajana Thakuri
Nepal is rich in forest resources. People therefore say that ‘green forests are the wealth of Nepal’. The forests of Nepal can be classified into these five parts – (1) sub-tropical evergreen, (2) Temperate Deciduous, (3) Temperate coniferous (4) Alpine vegetation and (5) Tundra vegetation. 1. Sub-tRead more

Given, Load (L) =800 N Effort applied (E) =600 N Length of inclined plane(l) = 5cm =0.05m Height of inclined plane(h) = 3cm=0.03m Mechanical Advantage (MA) = ? Velocity Ratio (VR) = ? Efficiency = ? We have, Mechanical Advantage = Load/Effort =800/600 =1.33 Now, Velocity Ratio = l/h = 0.05/0.03 =1.6Read more

Pedigree charts are diagrams that show the phenotypes and/or genotypes for a particular organism and its ancestors. ... These diagrams are used to determine the mode of inheritance of a particular disease or trait, and to predict the probability of its appearance among offspring.

Load (L) =800 N Effort (E) =600 N Length of inclined plane (l) = 5cm =0.05 m Height of inclined plane(h) = 3 cm = 0.03 m We have, MA= L/E =800/600 =1.33 Now, VR=l/h = 0.05/0.03 =1.67 Again, Efficiency = (MA/VR) ×100% =(1.33/1.67)×100% =79.64 %
Mechanics(Hydro dyanamics)
Samikshya Thakuri
An increase or decrease in flow rate will result in a corresponding increase or decrease in velocity. Smaller pipe causes a greater proportion of the liquid to be in contact with the pipe, which creates friction. Pipe size also affects velocity. Given a constant flow rate, decreasing pipe size increRead more

Lamarckism is the first theory of evolution, which was proposed by Jean Baptiste de Lamarck (1744-1829), a French biologist. Although the outline of the theory was brought to notice in 1801, his famous book “Philosophic Zoologique” was published in 1809, in which he discussed his theory in detail. LRead more

Physics
Dillisha Dangol
In general, solids posses greater densities than liquids. Therefore, for such liquids, the density decreases with an increase in temperature as the liquids expand on heating. However, in the case of water, it is different. Ice has lower density than water at the same temperature. As ice gets convertRead more

Jean Baptiste De Lamarck; a French biologist postulated the "Theory Of Inheritance of Acquired Characters", also known as Lamarckism. His theory was published in French Science Journal "Philosophic Zoologique" in 1809. Lamarckism theory is based on the idea that;changes acquired or developed by theRead more
Wave motion (Sound)
Sajana Thakuri
The general theory behind ear trumpets is to capture more sound and to provide some directionality towards the wanted sounds, while at the same time sheltering the ear from the unwanted background sounds. Like this This hearing aid helps to hear clearly by avoiding the unwanted background sounds.
Physics
Sajana Thakuri
Anomalous expansion of water refers to water's unusual ability to expand instead of contracting when cooled. In winters in very cold areas this ability causes water to form a layer of ice above the lakes/rivers/oceans. This layer of Ice acts as an insulation and prevents heat from escaping the waterRead more
Mechanics(Dimensions)
Sajana Thakuri
When an equation is dimensionally correct - it passes a kind of sanity check. Like if you’re calculating length and you expect the answer to be in feet - not square feet. Or you’re calculating the volume of an object and you expect the answer to be in liters. The essence of dimensional correctness iRead more

The problem is that, according to electrodynamics, if you change the direction of a charged particle this generates an electromagnetic wave, which would take energy away from the particle. An electron moving in a circle should be continually radiating electromagnetic waves, which means it would loseRead more
Population & Health

The world population is growing at an alarming rate. But overpopulation is seldom discussed as a public health issue. Just how many of us are there and how is our rising population affecting human health? Overpopulation already affects most countries in the world. And if rates continue as they are,Read more

Genetic diversity usually applies to intra species difference. while species diversity usually applies to inter species difference. Explanation: A lot depends on definitions. It is unclear what actually is referred to as a species. A species is generally a population of inter breeding organisms. WitRead more
Economics

There is no one definition of Economics which has a general acceptance. The formal roots of the scientific framework of economics can be traced back to classical economists. The pioneers of the science of economics defined economics as the science of wealth. Adam Smith (1723 -1790), the founder of eRead more

Lamarckism, or Lamarckian inheritance, also known as "Neo-Lamarckism",[1] is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. This idea is also called the inheritance of acquired characterisRead more
