If A and B are vectors then AxB=ABsin(AB). If A and B are not zero then AxB is zero if and only if sin(AB)=0 meaning the angle between A and B is a multiple of 180 degrees, in other words parallel.
A rigid body will remain in equilibrium when acted upon by a non-parallel coplanar force if the vector sum of all forces acting on the body is zero, and the vector sum of all torques (or moments) acting on the body is also zero. This condition is known as the equilibrium of forces and moments.
No, a particle cannot have zero speed and non-zero velocity simultaneously. Speed is the magnitude of velocity and if speed is zero, then velocity must also be zero.
Yes, you can have a situation where an object has a non-zero velocity but zero acceleration. This occurs when the object is moving at a constant speed in a straight line. On a velocity-time graph, this would be represented by a horizontal line at a non-zero velocity value and a flat line at zero acceleration.
For example, an object thrown upwards, when it is at its highest point. This situation is only possible for an instant - if the acceleration is non-zero, the velocity changes, and can therefore not remain at zero.
Yes, it is possible to have zero displacement and a non-zero average velocity. This can occur if an object moves back and forth over a certain distance so that the total displacement is zero, but the average velocity is non-zero due to the object covering distance in both directions.
Non-parallel forces are vector forces having an angle other than zero degrees or 180 degrees direction between them.
A non-regular quadrilateral can have either zero, one, or two pairs of parallel sides. If it has no parallel sides, it is called a trapezoid; if it has one pair of parallel sides, it is still considered a trapezoid; and if it has two pairs of parallel sides, it is classified as a parallelogram. Thus, the maximum number of parallel sides a non-regular quadrilateral can have is two.
To prove a trapezoid is isosceles, you need to show that the legs (the non-parallel sides) are congruent. This can be done by demonstrating that the base angles opposite these sides are congruent. You can use the triangle congruence postulates or the properties of parallel lines and transversals to establish the equality of these angles.
Non-parallel lines intersect at some point, parallel lines don't.
I think you meant to ask for finding a perpendicular vector, rather than parallel. If that is the case, the cross product of two non-parallel vectors will produce a vector which is perpendicular to both of them, unless they are parallel, which the cross product = 0. (a zero vector)
It is non-zero.It is non-zero.It is non-zero.It is non-zero.
When the lines of action of all the forces are not parallel to each other is defined as non parallel forces
A trapezium can have 0, 2 or 3 sides of equal length.0 equal sidesThis is the general state of a trapezium.2 equal sidesThe two parallel sides can never be equal.The two non-parallel sides can be equal. In this case, the trapezium is an isosceles trapezium.Or one of the parallel sides can be equal to one of the non-parallel sides. No special name.3 equal sidesThese would have to be the two non-parallel sides and one of the others. The trapezium is isosceles.
Any non-zero integer.Any non-zero integer.
Non zero one was created in 2009.
Non Zero Sumness was created in 2002.
no, if two lines are not parallel then the will eventually have to intersect.Alternate perspective:Yes, if two lines are non-parallel, they need not intersect in three dimensional space.
