A body is under the action of two forces 7 newton and 10 newton. Find the resultant of the two forces if the forces are parallel and act in the same direction

17 N

Explanation:

this is because in the calculation of vector /newtons

you must decide which direction is positive and the opposite direction will be negative,

so let's suppose right is positive,

and both the forces are in right direction,

so both are positive,

7 N + 10N = 17 N

but if one was in the opposite direction then, one would be negative

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
