my rank is 2578, can I join any stream of my choice?

What could be the cut off fer BITSAT this year?

the magnetic feild is perpendicular to the face or to the side

Find the missing f(x):

x       1  2  3   4    5

f(x)   2  5  9         32

We use the right hand rule when we want to find the direction of magnetic feild of a straight current carrying conductor.

It goes like this: point u r thumb in the direction of the current, then direction of the magnetic feild is the direction which u r curled fingers point.

Flemings left hand thumb rule gives u the direction in which the coil in a motor moves.

Here the thumb, index and middlefinger's r held mutually perpendicular to each other. Then the forefinger points direction of current, the middlefinger shows direction of magnetic feild, then the thumb shows direction of motion of the coil.

A curve xy=1 is rotated about the x-axis through an angle of 2 radians. Find the volume of the resultant solid between the points (a,b) and (c,d) whichlie on the curve.

Plz help me i need it urgently...................
