A
The horizontal force cancels out. The two 4Ns go in opposite directions. So they don't affect the outcome.
The Vertical force is 6N up - 2 N down = 4 N Up
Answer 4 N up
B
The horizontal and vertical forces cancel out. Each gives 3N - 3N =0
The net force is 0
C
You only have horizontal forces on this one
5N - 3N = 2N
The answer is 2N to the right.
Answer:
The formula is dimensionally correct.
Explanation:
Given

Required
Prove its correctness
Write out the dimension of each:
--- displacement
--- velocity * time
--- acceleration * square of time
The expression becomes:


Apply law of indices



Both sides of the equation are equal
False. Ray AB starts at point A and continues through and infinity beyond point B. Ray BA is the reverse. in the name of a Ray the starting point always comes first.
Answer:
Im pretty sure that its, the metals and nonmetals, electrons transferred.
Answer:
1. Equal.
Explanation:
Newton's third law of motion;
According to this law every action have its reaction with same magnitude but in the opposite direction.
If we push a wall with some amount of force then wall pushes back with same magnitude but in the opposite direction.This law tell us about action and reaction forces which are in same magnitude but in the opposite direction.
Therefore the answer will be 1.
1. Equal.
