What is relation between displacement and time?
Velocity is the displacement per unit time. V =dx/dt Note velocity and displacement are vectors and have direction.
How does the angle of insulation change between midday and evening affect the air temperature?
There is no such thing as the angle of insulation. If you mean the angle of incidence then the more direct the radiation then there will be more energy per unit area..
Is angle is a derived quantity?
From the Wikipedia article about the radian: "The unit was formerly a SI supplementary unit, but this category was abolished in 1995 and the radian is now considered a SI derived unit." The radian can be derived as the ratio between two lengths. That makes it a dimensionless unit.
What is angular speed measured in?
Usually radians per second. Any unit is appropriate, if it consists of (a unit of angle) divided by (a unit of time)
What is the unit weight of angle 50X50X6 mm thickness?
4.5 kg/m
If A and B are two unit vectors and is the angle between them Then A B is a unit vector Find?
Your question is kind of confusing, but if you're asking what the angle between two unit vectors A and B is, then the answer is: the inverse cosine of the dot products of A and B.
What is the difference between orthogonal and orthonormal vectors?
All vectors that are perpendicular (their dot product is zero) are orthogonal vectors.Orthonormal vectors are orthogonal unit vectors. Vectors are only orthonormal if they are both perpendicular have have a length of 1.
Are all unit vectors equal?
No. Their magnitudes are equal (that's why they're "unit" vectors), but their directions are different.
What are unit vectors used for in real life?
In real life unit vectors are used for directions, e.g east, north and up(zenith). The unit vector specifies the direction. Gyroscopes maintain a direction and keep things level. Whenever and where ever location is important, unit vectors are a part of real life. Whenever directions are important in your real life, then unit vectors are important. If everything was confined to move along a straight line, then unit vectors would not be important. If you can move in a plane, then unit vectors are important. Moving in space, unit vectors are more important. cars, ships and planes all move in space. Controlling and tracking these all involve unit vectors.
When do we use vector algebra in daily life?

Can the vector product of two vectors be negative?
no .....the scalar product of two vectors never be negative Yes it can If A is a vector, and B = -A, then A.B = -A2 which is negative. Always negative when the angle is between the vectors is obtuse.
Dot product of unit vectors of cartesian and cylindrical coordinate system?
Unit vectors are perpendicular. Their dot product is zero. That means that no unit vector has any component that is parallel to another unit vector.
What are the cartesian base vectors in mathematics?
They are unit vectors in the positive directions of the x and y axes.
What is angle and its unit?
Angle is the inclination between two lines or planes which have one one common point of contact and it's unit is degree or radian
Why a unit vector is aone type of vector but a vector is not a unit vector?
A unit vector is a vector whose magnitude is one. Vectors can have magnitudes that are bigger or smaller than one so they would not be unit vectors.
Can you add three unit vectors to get a unit vector does your answer change if two unit vectors are along the coordinate axes?
Yes., and their being along the coordinate axes does not change the answer.Consider the vectors: i, -i and j where i is the unit vector along the x axis and j along the y axis. The resultant of the three is j.
What is the difference between unit vectors and column vectors?
a unit vector is any vector with length or absolute value 1. A column vector is any vector written in a column of since we say an mxn matrix is m rows and n columns, a column vector is mx1 matrix.
