What else can I help you with?
What is my result if i calculate the magnitude of the resultant of a pair of 84 km h velocity vectors that are at right angles to each other?
If two vectors with equal magnitudes 'M' have perpendicular directions, then the resultant ismidway between them ... 45 degrees from each ... and the magnitude of the resultant isM sqrt(2).84 km/hr North + 84 km/hr East = 84 sqrt(2) = 118.794 km/hr Northeast (rounded).
What is the magnitude of the resultant of a pair of 5 unit vectors at right angles to each other?
A touch over 7. More exactly 7.0711.
For any triangle made of vectors will any pair of vectors that form its sides be equal vectors?
No. Only in the equilateral case. And then they will only be equal in magnitude, not direction.
Can 3 vectors of equal magnitude add up to give zero?
Yes. Just arrange them so that there is 120 degrees between the directions of each pair.
DrAw a pair of perpendicular lines?
A plus sign (+) would be a pair of perpendicular line segments.

Can you draw a pair of intersecting lines that are perpendicular?
a pair of intersecting lines that are perpendicular
Does a dodecagon has no pair of perpendicular sides but has pair of perpendicular sides?
The question contradicts itself. A dodecagon need not have any perpendicular sides.

A plus sign (+) would be a pair of perpendicular line segments.
Does a trapezoid have a pair of perpendicular lines?
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
What is a perpendicular diagonal?
A perpendicular diagonal is a pair of segments or lines that cross a polygon making a perpendicular
Has a kite got 1 pair of perpendicular sides?
No but its diagonals are perpendicular
What is cross-product and dot-product?
Cross products and dot products are two operations that can be done on a pair of 2-dimensional, 3-dimensional, or n-dimensional vectors. Both can be viewed in terms of mathematics or their physical representations.The dot product of two three-dimensional vectors A= and B= is a1b1+ a2b2 + a3b3. The definition in high dimensions is completely analogous. Notice that the dot product of two vectors is a scalar, not a vector. The dot product also equals |A|*|B|cosθ, where |A| and |B| are the magnitudes of A and B, respectively and θ is the angle between the vectors. This is the same as saying that the dot product is the magnitude of one vector multiplied times the component of the second vector that is parallel to the first. Notice that this means that the dot product of two vectors is 0 if and only if they are perpendicular.The cross product is a little more complicated. In three dimensions, A × B = . Notice that this operation results in another vector. This vector always points in a direction perpendicular to both A and B, and this direction can be determined by the right-hand rule. Physically, the magnitude of this vector equals |A|*|B|sinθ, or the magnitude of the first vector times the component of the other that is perpendicular to the first. So the cross product is 0 when the vectors are parallel.
Which picture shows a pair of perpendicular line segments?
