What are the two kinds of measure?
vectors and scalars.....
What are two kinds of compounds?
The two types of compound are molecular and ionic. An ionic compound commonly used is table salt, or NaCl. A molecular compound commonly used is water, or H2O.
When are two vectors identical?
Two vectors are identical when all their components are identical. An alternative definition, for vectors used in physics, is that they are identical when both the magnitude and the direction are identical.
What are the applications of Parallelogram law of vectors?
The law is used to add vectors to find the resultant of two or more vectors acting at a point.
Can sum of two vectors be numeric?
No, the sum of two vectors cannot be a scalar.
Can two vectors having different magnitudes be combined to give a zero resultant can three vectors?
Two vectors: no. Three vectors: yes.
Can the resultant of two equal vectors be of same magnitude as the two vectors?
Yes. This will happen if the two vectors are at an angle of 120 degrees.
Is it possible to combine two vectors of different magnitude to give a zero resultant if not can three vectors be combine?
Two vectors: no. Three vectors: yes.
What is the product of two vector quantities?
It depends on the type of product used. A dot or scalar product of two vectors will result in a scalar. A cross or vector product of two vectors will result in a vector.
Can the resultant of two vectors of the same magnitude be equal to the magnitude of either of the vector. How?
Yes - if the vectors are at an angle of 60 degrees. In that case, the two vectors, and the resultant, form an equilateral triangle.Yes - if the vectors are at an angle of 60 degrees.

When adding two vectors at right anglers the resultant of the vectors is the algebraic sum of the two vectors True or false?
false
Can the sum of the magnitudes of two vectors ever be equal to the magnitudes of the sum of these two vectors?
only if the vectors have the same direction
