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

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

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
