Question

"The black revolution in south africa was in against of depotism of white miniorities there " justify the statement​

Answer 1

Answer:

Hy mate here is your answer

Two methods to dot-product to compute the dot product are:

[1] ¯u⋅¯v=(ux)(vx)+(uy)(vy)+...

Where ux and vx are the x components, uy and vy are the y components, and so on.

[2] ¯u⋅¯v=|¯u||¯v|cos(θ)

where the magnitudes are |¯u|=√u2x+u2y+...and |¯v|=√v2x+v2y+... and θ is the angle between the two vectors.

To do this problem, you compute the dot-product using method [1]:

¯u⋅¯v=(1)(0)+(0)(−2)

¯u⋅¯v=0

This is a special case where the dot-product is zero and we instantly know that θ=π2 but let's proceed as, if it were not this special case.

Next, compute the magnitudes:
