line position vs staff position

If a reference line on a rigid body rotates through an angle , a point within the body at a position 'r' from the rotation axis moves a distance 's' along a circular arc where 's' is given by ..

Positive correlation means ______. => points can be approximated by a line with a negative slope or points can be approximated by a line with a positive slope or points that cannot be approximated by a line or points can be approximated by a curve o..

The rate of change of position of a particle in a particular direction gives the velocity of the particle. It may also be defined as the time rate of change of displacement of a particle. Velocity is a vector quantity. A motion is said to be uniform if the particle covers equal distances..

A player kicks a football from a position that is 12 yards from a sideline and 13 yards from a goal line. The ball lands 25 yards from the same goal line and 17 yards from the same sideline. How far was the ball kicked? => 20 yards or 15 yards or 10 yards or 13 yards o..

If a non vertical line has an inclination θ with the positive x -axis, then find the slope m of the line in terms of θ. => cosec θ or cot θ or tan θ or sin θ..

The slope of a line is defined as the tangent of the angle made by the line with the x-axis in the positive direction (anti-clockwise). If q is the smallest positive angle made by the line with the x-axis, then Slope = tan q = m. The slope of ..

Telephone Lines - The transmission lines used in telephony are of two kinds: open- wire and cable. The open-wire lines are gradually being superseded by cable construction, either overhead or underground, for two principal reasons. In the first place, many more circuit..

A line AB ↔ makes an angle of 60 o with the positive x -axis. What is the slope of any line parallel to AB? => 3 or 60 or 1 3 or π 3..

The lines of force or field lines 1) start from positive charges and end at negative charges. In the case of a single charge, they may start or end at infinity. 2) two field lines can never intersect each other. 3) contract longitudinally. 4) exert lateral p..
