A vector is an organism, often an insect, that transmits pathogens or parasites from one host to another, playing a crucial role in the spread of diseases. In contrast, a pest refers to any organism that is considered undesirable or harmful in a specific context, often causing damage to crops, livestock, or human health. While all vectors can be pests, not all pests act as vectors; some may simply cause harm without transmitting diseases. Thus, the primary difference lies in their roles: vectors facilitate disease transmission, while pests are generally defined by their negative impact on human activities or health.
write the point of differences between the follwing scalar and vector
Just the areas you are restricted to & there are some small differences on the tests.
They are a nuisance pest only, not a known vector.
IVCC is UK's vector control, look for their site.
Vector spaces can be formed of vector subspaces.
A tensor is a more general mathematical object that can represent multiple quantities at once, while a vector specifically represents magnitude and direction in space. Tensors have more components and can capture more complex relationships between quantities compared to vectors.
90 degrees
A null vector has no magnitude, a negative vector does have a magnitude but it is in the direction opposite to that of the reference vector.
They are the same.
Depends on the situation. Vector A x Vector B= 0 when the sine of the angle between them is 0 Vector A . Vector B= 0 when the cosine of the angle between them is 0 Vector A + Vector B= 0 when Vectors A and B have equal magnitude but opposite direction.
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
A unit vector is a vector with a magnitude of 1, while a unit basis vector is a vector that is part of a set of vectors that form a basis for a vector space and has a magnitude of 1.
