New to physics.

Can you help me to answer these question? Im an late enrolee, trying to catch up. Thanks!

If vector A is directly upwards with a magnitude of 100N and vector B is directly downwards with a magnitude of 230N what is the sum of the two vectors? O 30N upwards O 130N upwards O 20N downwards 130N downwards Refers to the downward force exerted by gravity on an object Mass Weight Acceleration due to gravity Newtons Which of the following is not a vector quantity? Acceleration Momentum Force O Electric Field Electric Current If a boomerang is thrown 10meters in a straight line motion, then returns exactly to the spot where it was thrown, what is the displacement of the boomerang? Q -10m Om O 10m O 20m
