What is a vector with a magnitude of one and with no unit?

A. Single vector

B. Unit vector

C. Dot vector

D. Scalar vector

Let vector V 1 = -6.5ihatbold + 5.5jhatbold and vector V 2 =7.5ihatbold -2.5jhatbold. Determine the magnitude and direction ofeach of the following. (Give angles as measured counterclockwisefrom the +x axis (answers will be between -180° and +180°).)

(a) V1
vector:
magnitude:
angle:

(b) V2
vector:

HELP PLEASE!

Vector A has a negative x component 3.00 units in length and a positive y component 2.00 units in length. (a) Determine an expression for  in unit-vector notation. (b) Determine the magnitude and direction of . (c) What vector  when added to  gives a resultant vector with no x  component and a negative y component 4.00 units in length?

If (vector) B is added to (vector) C=3.0i + 4.0j, the result is a vector in the positive direction of the y axis, with a magnitude equal to that of (vector) C. What is magniatude of (vector) B?
