    Why does heat reflect sunlight? (ie: mirages)

    Usually in hot desert, because of the hotness of the sand the density of the air which is close to it decreases and as we go higher/upper the density of air relatively increases so we can imagine them as layers.(as the pic has shown) As we know that light changes its direction and speed...

    Resultant of thirty vectors of a polygon

    equation, square of resultant, R2 = Rx2 + Ry2 [b] interior angle of a polygon = (n-2)* 180°/n = (30 - 2)* 180°/30 = 168° components on X axis: Ax1 = 20* cos 168° Ax2 = 20* cos (168°+168°) . . . . Ax30 = 20* cos...

    Can We Have Lower Valued Prefixes in Binary?

    Why they had to add three more bits to six? What kinds of problem we could have possibly faced if six bits made up bytes were still working?

    Can We Have Lower Valued Prefixes in Binary?

    In binary can we have a value with "deci" "centi" "mili" or more lower valued prefix? i have learned that, 1 Kilo Byte = 210 byte 1 Miga byte = 220 byte . . . . 1 Yotta byte = 224 byte Now my question is, can we have a DECI, CENTI, MILI bytes? i assume the answer could be negative...

    What is the Origin of the Trigonometric Identity?

    Sin (a + a) = sin a cos a+ cos a sin a => Sin 2a = 2Sin a Cos a => SIN B = 2 Sin (B/2) Cos (B/2) [2a = B] . . . . (i) Cos (a + a) = cos a cos a - sin a sin b => cos 2a = cos^2 (a) - sin^2 (a) => cos 2a = (1 - sin^2 (a) ) - sin^2 a => cos 2a = 1 - 2sin^2 (a) => 1 - cos 2a = 2s n^2 (a)...

    Is infinity plus or minus one possible?

    infity means INFINITY, dude! Just plusing or minusing some lil value rather than another infinity doesn't really bother to hamper its value at all... For example when you fill a bottle with sea water, the water level does not really change that negligible, right? And infinity is much more huge...
