Is speed described fully by magnitude and direction?
Speed usually means just the magnitude, but if you mean velocity, then yes. Make sure you're specific on the direction (example: 45 degrees counter clockwise of east) because some teachers are really picky about that.
Area is scaler or vector quantity?
Well it is technically a vector because it has a magnitude and a direction on zero degrees. Reactive power will have a direction of either + or - 90 degrees and apparent power will be the vector sum of the real and reactive power.
Under what circumstances can a vector have components that are equal in magnitude?
(Magnitude of the vector)2 = sum of the squares of the component magnituides Let's say the components are 'A' and 'B', and the magnitude of the vector is 'C'. Then C2 = A2 + B2 You have said that C = A, so C2 = C2 + B2 B2 = 0 B = 0 The other component is zero.
Under what circumstances would a vector have a components that equal in magnitude?
When it's pointing exactly northeast, northwest, southeast, or southwest.That is, when its direction is exactly 45 degrees from both the 'X' and 'Y' axes.
Examples of some quantities that are scalar and vectors?
A vector has a magnitude and a direction. A scalar is only a magnitude. For example, If I say that I am going 60 m/s, that I have described my speed as a scalar value. If I say I am going 60 m/s due east, I have described both my speed and direction and therefore it is a vector.
Can a vector resultant have a negative direction I have a statics problem and the answer is 77.31 deg in the III quad Negative or Positive Or is the answer 257.31 deg from the horizonal?
A vector has both magnitude and direction. The magnitude is always positive, by convention, but this is not cast in stone. So you can have in your case a positive magnitude with a direction 257.31 degrees, which is the same as a positive magnitude 77.31 degrees in quadrant III, but the first way is more conventional. One could also say a negative magnitude at 77.31 degrees, in which case the negative sign implies a 180 degree reversal. So there are many choices, and you seem to have a good handle on this.
How can you find the magnitude and the length of the resultant?
A ship is traveling 155mph due south .Opposing current 35mph at 20 degrees southwest . Find resultant magnitude and direction of ship's true course

The vector has a magnitude of 11 and a direction of 20 degrees. What is the magnitude of the x component?
Assuming the 20 degrees are measured counterclockwise, starting from the x-axis (this is more or less standard), you can calculate the x-component as 11 x sin(20). Make sure your calculator is set to degrees first.
What is the city or the country name located at this diection 45 degrees north75 degrees west?
45 N 75 W is Ingleside Ontario K0C 1M0 Canada
Can two displacement vectors of the same length have a vector sum of 0?
Yes, as long as the direction is exactly opposite (180 degrees from each other). A vector has both magnitude and direction.

What does it mean when an angle is negative?
An angle is a measure of turn. the amount of turn is the magnitude, measured in degrees, and direction of turn can be clockwise or anti-clockwise. A positive angle turns in an anti-clockwise direction while a negative angle turns in a clockwise direction.
A boy on a treasure hunt walks 10 paces west then 20 paces north then 27 paces east. what is the boy s resultant displacement give magnitude and direction?
When we add up the vectors we are left with 17 paces east and 20 paces north. Tan(x) = opp/adj = 17/20 x = 40.4o - remember that this is degrees from North We can then work out the distance using trig or pythagora's theorem. I'll use pythagora's theorem: srt(20^2 + 17^2) = 26.2 paces ok, but is the direction 26.2 paces North? because you have to give magnitude and direction. The magnitude is 26.2 paces The direction is 40.4 degrees we measure degrees clockwise from north - exactly like on a compas or protractor. Thirty
Are scalars a measured quantity?
A scalar is anything that has only a magnitude. Usually people contrast scalars with vectors. Speed and temperature are scalars. They only have a magnitude (50 mph or 32 degrees) Velocity and acceleration are vectors. They have both a magnitude and a direction (50 mph north, 9 m/(s^2) downwards )
Under what circumstances can a vector have components that are equal in magnitude?
(Magnitude of the vector)2 = sum of the squares of the component magnituides Let's say the components are 'A' and 'B', and the magnitude of the vector is 'C'. Then C2 = A2 + B2 You have said that C = A, so C2 = C2 + B2 B2 = 0 B = 0 The other component is zero.
A duck waddles 2.5 m east and 6.0 m north what are the magnitude and direction of the duck's displacement with respect to its original position?
6.5 m at 67 degrees north of east
