Pure Rotational Motion- in such a motion‚ a rigid body rotates about a fixed axis. Every particle of the body moves in a circle‚ which lies in a plane perpendicular to the axis‚ and has its centre on the axis. For e.g.‚ in an oscillating table fan or pedestal fan‚ the axis of rotation is horizontal. This axis has an oscillating sideways movement in a horizontal plane about the vertical through the point at which the axis is pivoted. (3) Combination Of Translational And Rotational Motion- for e.g

5. Managerial Grid The x/y axis on the grid consist of two behavior dimensions‚ concern for people and concern for production. Concern for people is the degree to which a leader considers the needs of employees when deciding how tasks or jobs should be done. This can be personal or professional development. This behavior dimension moves along the y-axis. Concern for production is the degree to which a leader emphasizes objectives and productivity goals when deciding how tasks or jobs should

than the First. In this essay‚ I would like to talk about “To what extent should the Axis Powers be responsible for the outbreak of World War Two?’. Actually‚ I think that to a large extent‚ the Axis Powers (Germany‚ Italy and Japan) were responsible for the outbreak of the Second World War. There are mainly five causes of World War Two. And four of these five causes were related to the Axis Powers. Firstly‚ the Axis Powers were discontent towards the Paris Peace Treaties. The defeated powers‚ especially

the quadratic will always be equal to zero. This will result in the parabola cutting the axis once‚ or twice in the same place‚ creating a distinct root or two of the same root. For PROOF 1‚ the equation y=a(x-b)2 is used. PROOF 1 y = 3 (x – 2)2 = y = 3 (x2 – 4x + 4) = y = 3x2 – 12x + 12 ^ = b2 – 4ac = (-12)2 – 4 x 3 x 12 = 144 – 144 = 0 The discriminant is equal to zero. The parabola touches the x-axis at (2‚ 0) and as a in the equation is a positive value‚ the parabola curves upwards.

Vertical Axis — Leveling the Instrument The first step in calibrating an instrument is to see that it is properly leveled. If an instrument is not leveled‚ then the vertical axis is not plumb‚ and that is the axis about which horizontal angles are measured. The instrument
