Answer:
Dry Cell : It is a primary cell based on Leclanche cell invented by G. Leclanche in 1868. In a primary cell, the electrode reactions cannot be reversed by an external source of electrical energy. In this cell, the cell reaction takes place only once i.e., this cell is not rechargeable. It is.generally used intorched, transistors, radios, calculators, tape recorders etc. It consists of a hollow zinc cylinder which is filled with a paste of NH .
Voltaic Cell Working. The working principle of voltaic cell depends upon the principle that, whenever two dissimilar metals are immersed inside an electrolyte solution, the more reactive metal will have a tendency to dissolve in the electrolyte as positive metal ions, leaving electrons behind on the metal plate.
Answer:
Explanation:
Given
Initial Flow of water
density
Initial velocity
Final velocity
Initial mass flow rate
Let area of cross section of Two streams after striking be A
Conserving Flow
or Flow rate after splitter splits in to half
conserving momentum in x direction
Final momentum in x direction
Change in momentum
F=1409.24 lbf
change of momentum in Y direction is zero as the two flows oppose thier motion after striking with splitter.
From that particular short list, the item that best describes a plane
is the surface a flat table (or of any other flat thing).
-- The edge of a desk is a piece of a straight or curved line.
-- A curve in a road is a piece of a curved line.
-- The intersection of two walls is a piece of a straight line.
Answer:
It takes <u>2.93 s</u> for the object to reach ground from the height of 42 m.
Explanation:
Given:
Displacement of the object is,
As it is dropped, initial velocity of the object is,
Acceleration of the object is equal to acceleration due to gravity and is equal to,
Now, using Newton's equation of motion and plugging in the values, we get:
So, it takes 2.93 s for the object to reach ground from the height of 42 m.
