A vector with magnitude = 70 , directed 20° above or below horizontal,
has a horizontal component of
70 cos(20°) = 65.778 (rounded)
As you have written it, the quantity "96 percent relative humidity" has only a magnitude. If you can find a reasonable and meaningful way to relate it to a direction, then it'll also have a direction. I notice, however, that over several decades of broadcast and printed weather conditions and forecasts, I have never once seen a direction stated as part of the relative humidity, and that never seemed to leave it lacking in information. So I'm guessing that you probably won't be able to do it.
A crosswind is any wind that is not in the same direction as travel. The crosswind component is perpendicular to the direction of travel ( 90 degrees). Mathematically, the crosswind component is the speed times the sine of the angle relative to the direction of travel. For example if a plane travels NORTH and there is a crosswind from the EAST ( 90 degrees) at 20 mph the crosswind component is 20 mph ( 20 sin90 = 20) For another example if a plane travels NORTH and there is a crosswind from the NORTHEAST ( 45 degrees) at 20 mph the crosswind component is 14.1mph ( 20 sin45 = 14.1)
This is used to represent the relative size of the components.
A ratio is a quantity that denotes the proportional amount or magnitude of one quantity relative to another. by swety
Scalar QuantitiesMost of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time (minutes, days, hours, etc.) represent an amount of time only and tell nothing of direction. Additional examples of scalar quantities are density, mass, and energy.Vector QuantitiesA vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis, as shown in Figure 1. Using north/south and east/west reference axes, vector "A" is oriented in the NE quadrant with a direction of 45 north of the o EW axis. G iving direction to scalar "A" makes it a vector. The length of "A" is representative of its magnitude or displacement.Another AnswerA scalar quantity refers only to the magnitude of the quantity and answers the question how much. Ex. height, weight, volume, and the like. 2 lbs of sugar is scalar, 4 m long is scalarA vector quantity refers to both magnitude and direction and answers how much and where is it going, (in that sense)Ex. forces, velocity. 200 km/hr at N30degE is a vector, the force required to push a drum up or down a ramp is a vector, the force exerted by the cue stick in billiards is a vector a scalar is a number, like a distance... like the moon is 300.000km away from earth.a vector is a number AND a direction. It's like "moving east at 100km/h"while "moving at 100km/h" alone is a scalar.The idea is that a scalar has only ONE dimension, while a vector has several.
The initial velocity is sqrt(5) times the vertical component, and its angle relative to the horizontal direction, is 0.46 radians (26.6 degrees).

Magnitude means relative importance or relative size or extent - such as in the magnitude of the hurricane. Relative in this case means true to a certain degree.

It means Noun A quantity having direction as well as magnitude, esp. as determining the position of one point in space relative to another. Not really sure about a sentence
Because it is: * A property of physical objects * Something that can be measured (or calculated from other quantities) Hmm, it is certainly not a physical quantity that is unique to the object! Velocity is relative to some other object. Thus, the can he threw traveled at 12m/s relative to the tree but 220m/s relative to that car.
Force = Mass x AccelerationMake a triangle using the tip-to-toe method:[squareroot(X-component^2 + Y-component^2)]/mass = AccelerationAs for the angle, again look at the traingle you made and thetangent(angle) = Opposite/adjacentSOInverseTan(opposite/adjacent) = Angle
In geology, the least common type of boundary is transform boundary. Its relative motion is predominantly horizontal in either sinistral or dextral direction.
Work is done when a force acts on an object and causes it to be displaced. Only the force that acts in the direction of the displacement can be considered.When you walk across the room, your legs apply a horizontal and a vertical force (relative to the ground) to displace your body. The horizontal is the pushing forward. The vertical is the slight bobbing up-and-down we all do when we walk or run. So there are two force components to consider: the vertical and the horizontal.For the vertical component of the force, when you go up, you are doing work on your body. When you go down, work is being done to your body because gravity pulls you down. So the net work attributed to the vertical motion is zero.The horizontal component of the force always acts in the direction of motion. This horizontal component is the only one responsible for doing any work.The bobbing up-and-down motion is a waste of energy because it doesn't contribute to working. This is why running coaches tell you to stop bobbing. If you are trying to efficiently move across a horizontal distance, there is no point to moving up-and-down vertically.
Magnitude can only be a real number - that is 0 to infinity. A negative magnitude would imply a direction, which is what a vector is about: magnitude and direction. It's like temperature, in actuality there is no negative, only 0 and up (the Kelvin scale demonstrates this better than Fahrenheit or Celsius as they are meant to be relative, not absolute scales. The Kelvin scale says absolute 0 = no molecular movement at all. You can't have negative molecular movement {either it's moving or it's not}, the Kelvin scale is a good example as a scalar, it can be 0 or higher, no negatives.
