The main difference between a scalar and a vector quantity is: A) Magnitude B) Direction C) Unit

Which formula can be used to find the angle of the resultant vector?

The components of a vector are the parts of the vectors that are to each other.

A resultant vector is the of two or more vectors.

Two vectors, X and Y, form a right angle. Vector X is 48 inches long and vector Y is 14 inches long. The length of the resultant vector is ____ inches.

Which equation represents the Pythagorean theorem, which can be used to find the magnitude of resultant vectors? R = A + B, R = A x B, R2 = A2 x B2, or R2 = A2 + B2

A helicopter flies 250 km on a straight path in a direction 60° south of east. The east component of the helicopter's displacement is ⇒

In order to use the Pythagorean theorem to find the magnitude of a resultant vector, which must be true regarding the two initial vectors?
