Why is an electric field strength a vector quantity?
for a vector quantity it must have both magnitude and direction and since it has both magnitude and direction it is therefore considered a vector
What is coplanar vector?
In geometry a vector is used to make the equations easier to understand and to figure out. Velocity and force are examples of vectors. For a vector to be coplanar there must be two or more and they must be linearly dependent. Coplanar vectors have proportional components and their rank is 2.
What is vector in plant pathology?
A vector is an organism that can carry pathogen(= disease causing organism) from infected plant to a health plant. Generally, a vector is an insect, a nematode, a fungi, or insect like organisms e.g. spider mites. To qualify as vector, the organism must have the ability to acquire the pathogen, must be able to retain the pathogen for some length of time and lastly it must be able to inject it into a suitable/susceptible plant. The relationships between the vector and pathogen can be described as simple if the pathogen does not circulate or replicate in the vector or complex if the pathogen replicates or circulate in the vector. In the latter case, the vector also acts as the host of the pathogen.
Can two vectors of unequal magnitude add up to give the zero vector?
No. The vector resultant of addition of vectors is the vector that would connect the tail of the first vector to the head of the last. For any set of vectors to add to the zero vector, the endpoint of the last vector added must be coincident with the start point of the first. Therefore for the sum of only two vectors to have a chance of being the zero vector, the second vector must be in a direction exactly opposite the first. So you can tell that the result of adding the two vectors could only can be zero vector if the two vectors were of two equal magnitude.
In describing a vector what must you describe besides the magnitude.?
Its directiondirection
