Subtracting 2 Vectors
This is where things obtain a bit more interesting. What we required to note here is in which in Physics a negative sign simply means "in the opposite direction." We can take A - B and simply modify it into A + -B. The negative sign on the B just means that we will require taking the original vector B and pointing it in precisely the opposite direction (180° from where it's pointing right now. Then we will easily add them just such as we did in the previous diagrams (touching head-to-tail of course!)
a jet of engine on a test tube takes in 20kg of air per second at a velocity of 100m/s and burns 0.8kg of fuel per second.after compression and heating the exhaut gases are ejected

Logan, whose mass is 18 kg, sits 1.20 m from the center of a seesaw. If Shiro must sit 0.80 m from the center to balance Logan, what is Shiro's mass?
Actually vectors are divisible but not directly. A vector is multiplied by the inverse of the vector to be divided.In other way, its magnitude an be divided and multiplied by a uni
