What is the magnitude and direction of the vector JK given points J(100) and K(-23)?
The magnitude of vector JK is given by the distance formula, which is the square root of [(change in x)^2 + (change in y)^2]. So, √[(100 - (-23))^2 + 0^2] = √(123^2) = 123 units. The direction can be represented using trigonometric functions like tangent or using the arctan of the slope, which is (0 - 100) / (0 - (-23)) = -100/23.
What else can I help you with?
Does the magnitude of a vector refer to its length or distance?
The magnitude of a vector refers to its length, which is a scalar quantity representing how "long" the vector is in a given direction. Distance, on the other hand, refers to the separation between two points in space.
Is 5m a vector?
If a direction is given, it is a vector. Otherwise it is a scalar.
What is the magnitude of the vector 15 ft s down?
The magnitude of the vector is simply the length of the vector, which is 15 ft. The direction given as "down" does not affect the magnitude, only the direction.
What two quantities are neccesarz to determine a vector quantities?
It is necessary to know the magnitude and the direction of the vector.
What is the magnitude of the vector 75 mph to the north?
The magnitude of the vector 75 mph to the north is 75 mph. Magnitude refers to the size or length of the vector, so in this case, it is simply the speed given in the direction of north.

How can you find a unit vector in the same direction as the given vector?
Divide the vector by it's length (magnitude).

If an object is speeding up to the right what direction does its velocity vector point?
The velocity vector of an object that is speeding up to the right points in the same direction, to the right. Velocity is a vector quantity that includes both magnitude (speed) and direction, so as the object accelerates, the velocity vector will align with the direction of motion.
What two quantities are neccesarz to determine a vector quantities?
It is necessary to know the magnitude and the direction of the vector.
What is the magnitude of the vector 75 mph to the north?
The magnitude of the vector 75 mph to the north is 75 mph. Magnitude refers to the size or length of the vector, so in this case, it is simply the speed given in the direction of north.
What is the name given to the physical quantity which can be completely described by specifying both magnitude and direction?
The physical quantity that can be completely described by specifying both magnitude and direction is called a vector. Vectors are represented by arrows, where the length represents the magnitude and the direction represents the direction.
What is defined as the speed in given direction?
Velocity is defined as the speed in a given direction. It is a vector quantity that includes both the magnitude (speed) and direction of motion.
Is speed velocity in a given direction?
Yes , speed in a given direction is called velocity. Velocity is a vector quantity that is it has both magnitude as well as direction.
How to find the direction of vector when the magnitude is given?
You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions. You need some additional information to make conclusions about the direction.You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions.

What does the length of a vector arrow reprsent?
The length of a vector arrow represents the magnitude or size of the vector. It indicates how much of a quantity is being represented by the vector in a given direction.
