Take the example of a satellite moving around the earth:
In this case, the satellite is moving in a circular path and the centripetal force is provided by the gravitational force of the earth. At every point in the circular path, the centripetal force acts at right angles to the direction of motion of the satellite, i.e. the force and displacement are perpendicular to each other.
therefore Ɵ = 90 0
W= Fs cos Ɵ
= Fs cos 900
= Fs 0
=0
To minimize work, the angle between force and displacement should be 90 degrees (perpendicular). This is because work done is calculated as the dot product of force and displacement vectors, and the cosine of 90 degrees is 0, resulting in zero work. To maximize work, the angle should be 0 degrees (parallel), as the cosine of 0 degrees is 1, resulting in maximum work done.
Work done by a force when the force is in the direction of displacement is calculated as the product of the force and the displacement, multiplied by the cosine of the angle between them. Mathematically, work done (W) = force (F) × displacement (s) × cos(θ), where θ is the angle between the force vector and the displacement vector.
You measure it. Depending on the information provided, you can also calculate it, for example using trigonometry. ======================== Work done= Force vector . Displacement vector=Force*displacement*cos a, where a is the angle between the force and the displacement. So you have the values of work force and displacement then you can do the cosine inverse of the ratio of work done to the product of the force and displacement. That will give you the angle.
The force multiplied by the displacement is equal to the work done. This relationship is described by the equation: Work = Force x Displacement x cos(θ), where θ is the angle between the force and displacement vectors.
Zero, in this case acting force is perpendicular to the direction of displacement... Reason..... It is because here the angle is 90 degree and when there is an angle then the force is equal to F cos x * d= F *cos 90*0= 0 Therefore work done=0

If the angle between the displacement and force applied is less than a right angle, then it is Positive Work done. If the angle between the displacement and the force applied is greater than a right angle then it is Negative Work done. If the displacement and force are at right angles, or either is zero, then it is Zero Work done.
Work = Force * displacement if the displacement and the force are parallel - work is positive if force and displacement are in the same direction, negative if they have opposite direction. At an angle Work = Force * displacement * cos(θ) where θ is the angle between the force and displacement vectors.
amplitude
it is the dot product of displacement and force . i.e. Fdcos(A) where F is the magnitude of force , d is the magnitude of displacement and A is the angle between them

pythagorean theorem
The force multiplied by the displacement is equal to the work done. This relationship is described by the equation: Work = Force x Displacement x cos(θ), where θ is the angle between the force and displacement vectors.
The question cannot be answered. i72 metres is a measure of linear displacement or distance whereas an angle is angular displacement. An angle is measured in degrees or radians, not units of length. If you extend the arms of the angle, the legnth between their ends will increase! Same angle, different length.
You are mixing up 'phase angle' with 'angular displacement' (or 'phase displacement'); these are two completely different things. The term you should be using is 'angular displacement', which is the angle by which the secondary line voltages lagthe primary line voltages. The '7' indicates that this is 7 times 30 degrees; or 210 degrees.
Zero, in this case acting force is perpendicular to the direction of displacement... Reason..... It is because here the angle is 90 degree and when there is an angle then the force is equal to F cos x * d= F *cos 90*0= 0 Therefore work done=0
