any length between 1.5 and 8.5 meters depending on the angle between the vectors.
find the dot product of the two vectors to find the magnitude.
e.g. two vectors
a x
b . y
c z
gives a.x+b.y+c.z= your final answer. The dots mean times by (btw)

Centi is a factor of one hundredth; therefore 35 cm is .35m. Add 5m and .35 m is 5.35m.
5m/s
-7m - 3m + 5m = -5m
5m = 40m = 40/5m = 8
No, 5m is a scalar quantity because it only has magnitude (5) and no direction. Vectors are quantities that have both magnitude and direction.
5m is a scalar quantity. Scalars have only a magnitude or size and no specific direction. On the other hand, vectors have both magnitude and direction.
The combined displacement vector will have a magnitude of 8m. This is found by simply adding the magnitudes of the two original displacement vectors together (3m + 5m = 8m), since they are in the same direction.
Speed is the rate at which an object covers a distance, velocity is the speed of an object in a specific direction, and acceleration is the rate at which an object's velocity changes. Speed is a scalar quantity, velocity is a vector quantity, and acceleration is also a vector quantity.

The magnitude of the weight of the man is 980N.
Knowing the directions of the forces is important because forces are vector quantities, meaning they have magnitude and direction. The net force is the vector sum of all forces acting on an object, so it is crucial to account for both magnitude and direction in order to accurately determine the resulting motion of the object.

If you have lifted the object 5m off the ground, you would have pulled 10m of rope through the pulley system. This is because as the object gets lifted, the rope length on both sides of the pulley decreases by the same amount.
8m in the same direction.
