The sum and difference of two non zero vectors are A=(Axi + Ayj + Azk) and B=(Bxi + Byj +Bzk) are perpendicular to each other. show that the magnitude of the two vectors are equal.

How to calculate voltage drop in a series circuit

Convection occurs when thermal energy is transferred by the movement of

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
