c) Lithium (Li) Lithium is the lightest metal with a density of 0.564 g⋅cm−3 and it is also the least dense solid element.
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
MA=1.33 VR=1.67 Efficiency=70.64 %
Here, 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 MA=? VR=? Efficiency =? 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 % HENCE, MA=1.33 VR=1.67 EffRead more

In Lamarckism: The inheritance of such acquired characteristic means its reappearance in one or more individuals in the next or in succeeding generations. The characters acquired during the lifetime of an individual are transmitted to its offspring. In the offspring, these modifications become pronoRead more
On the basis of zones, forests in Nepal are categorized into 5 types. They are: 1)Trophical zone forest(upto 1000m) 2)Subtropical zone forest(1000m-2000m) 3)Temperate zone forest(2000m-3000m) 4)Sub-alpine zone forest(3000 m-4200m) 5)Alpine zone forest (4200 m to 5000 m) Furthermore, the forest of NeRead more
The cost concept of accounting states that all acquisition of items (such as assets or things needed for expending) should be recorded and retained in books at cost. Thus, if a balance sheet shows an asset at a certain value it should be assumed that this is its cost unless it is categorically stateRead more
