Solid block type construction of Lead acid batteries:
In the solid block type battery the electrolyte is completely absorbed into a compressed block consisting of porous plates and separators.
The plates are completely supported and therefore a more porous active material paste can be used, this gives better absorption and an enhanced electrochemical activity.
The support given to the plates means practically no distortion and no shedding, therefore no sludge gap is required, all the space inside the cells being used for the plates.
All of these advantage result in a battery that is stronger, less susceptible to vibration damage and has a higher capacity to weight ratio than its conventional counterpart.
Inertia: the resistance an object has to a alter in its state of motion. Newton's first law of motion declares that force is NOT required to keep an object in motion. Slide
Dirac constant; Planck constant, modified form; hbar A sometimes more convenient form of the Planck constant, explained as hbar = h/(2 pi).
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
What is Acoustic Holography? Acoustic holography is a technique used to evaluate the sound field near a source through measuring acoustic parameters ahead of the source through
Three similar coils, each having a resistance of 8Ω and an inductive reactance of 8Ω are connected (a) in star and (b) in delta, across a 415V, 3-phase supply. Calculate
A uniform spring of length 2m and mass 200gm is under a tension of 800N. Find the speed of transverse wave in the string.
a car of mass 800kg is pulling a trailer 300kg where sin a=1|200.Resistance to motion(apart from gravity) is 1.5N per kg of mad for each vehicle.calculate the pulls of the engine
sir in books like hc verma i have seen if centre of mass remains at rest... then mx = mX...how?
