Show previous answers

M replied | 16/03/2016

The Gauss' Law is used to find electric field when the charge is continuously distributed within an object with symmetrical geometry, such as sphere, cylinder, or plane. Gauss' law follows Coulomb's law and the Superposition Principle.

The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux through an area is defined as the electric field multiplied by the area of the surface projected in a plane perpendicular to the field.

Vikash Lomash replied | 16/06/2016

source (S), gate (G), drain (D), and body (B).

The main advantage of a MOSFET over a regular transistor is that it requires very little current to turn on (less than 1mA), while delivering a much higher current to a load (10 to 50A or more).

S.shekar replied | 13/05/2016

to avoid the effect of hammering of water on the inner surface of pipes other wise the pipe will burst if flowing water is stopped immedietly. this is controlled by surge tank by which we can control the pressure of liquids in pipes. shortly we can say to avoid hammering effect of water or liquids.

Rohit replied | 21/05/2016

We provide a surge tank because, just in case if someone suddenly closes the outlet valve while the water is flowing through the pipe, it will produce an effect knon as water hammer which will destroy the pipe. If a surge tank is there then the water will go and rise in surge tank Ra ty her than producing water hammer. It's a kind of fail safe system.

Girish replied | 15/03/2016

when physical state of conductor remain same then current flowing through the conductor will be directly proportional to the potential different applied across it. But understand one thing this law is strictly applicable to the devices which follows linear characteristics.

Vikash Lomash replied | 16/06/2016

Ohm's Law deals with the relationship between voltage and current in an ideal conductor. This relationship states that: The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

Cast iron is a brittle material which has high strength in compression and as we know pillars are subject to compressive load that's why cast iron is used in pillars.

Force is vector quantity.
F=mass×acceleration . Where mass is magnitute and acceleration is direction .
Vector quantity has both magnitude and direction .
Hence Force is a vector quantity.
Force is applied on a particular direction this makes force a vector quantity

Priyanka replied | 14/04/2016

As F=m*a, a product of mass and acceleration. Acceleration is a vector quantity whereas mass is a scalar quantity. Product of scalar and vector quantity is a vector quantity. This shows that force is a vector quantity.

Newtons first law of motion states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.Also known as law of Inertia.

newtons first law of motion mainly describes about inertia i.e, when a body is in motion or rest it continues it condition until an external force acts on it for example when bus moves we suddenly jump backwards
