Question

if A^--> + B^--> = c^-->
under what conditions A² + B ² will be equal to C² (--> mean velocity)​

Answer 1

Answer:

When A and B are perpendicular to each other

Explanation:

When A and B will be perpendicular to each other. This is because if they are perpendicular they will form a right angled triangle with A and B as base and perpendiculars and C as Hypotenuse.

we know, hyp^2=base^2+perp^2

so C^2= A^2+B^2
