**physis**

The magnitudes of the four displacement vectors shown in the drawing are A = 13.0 m, B = 11.0 m, C = 12.0 m, and D = 27.0 m. Determine the magnitude and directional angle for the resultant that occurs when these vectors are added together.

**AP Physics**

Consider the vectors A = 2.00 i + 7.00 j and B = 3.00 i - 2.00 j. (a) Sketch the vector sum C = A + B and the vector subtraction D = A - B. (b) Find analytical solutions for C and D first in terms of unit vectors and then in terms of polar coordinates, with angles measured ...

**Science**

We have a problem in AP Physics that we just can't get. It has to do with vector addition. The problem is: If aA+bB+C=0, find the magnitudes of a and b. *A, B, and C are vectors* *i and j are unite vectors* A=(6.0i-8.0j)units B=(-8.0i+3.0j)units C=(26.0i-19.0j)units How is ...

**URGENTTT!!**

I need to use the scalar triple product. but i dont have any vectors? how am i supposed to know what the vectors all coming from one corner are?? Q:Calculate the volume of the parallelepiped with vertices at: (9,4,3), (7,12,2), (12,5,6), (3,-4,0), (10,13,5), (1,4,-1), (4,5,2) ...

**Physics (vectors)**

Given vectors A= (Axi + Ayj), B= (Byj+Bzk) and C= (Cyj + Czk). a) find the triple product of these vectors defined by A dot (BxC) in terms of the vector components. I get 0 as the answer. b) is the result found in a) a scalar of a vector? since I had to multiply finally by the...
