What else can I help you with?
Is pressure a scalar quantity justify with an example?
Yup! We know that the scalar quantity is a quantity which is having magnitude but not having "DIRECTION" pressure is a scalar quantity for the reason that it's not having any direction Means it is directionless...... Have you ever heard saying anyone that the pressure applied was 730 torrs in west , east or north south direction?????????> No, it is IMPOSSIBLe.....
Can the magnitude of the difference between two vectors ever be greater than the magnitude of either vector?
Yes, the magnitude of the difference between two vectors can be greater than the magnitude of either vector. This can occur when the vectors are in opposite directions or have different magnitudes such that the resulting difference vector is longer than either of the original vectors.
Can the magnitude if the difference between two vectors ever be greater than the magnitude of their sum?
yes,if the components are making angle 0<=theta<=90 no ,the magnitude of vector can never attain a negative value |a|=square root of both components which always gives a positive value
How do you find the direction of a cross product vector?
Think of a screw-thread, threaded just like a screw that you might use to screw a hook into a piece of wood. In the US, all woodscrews are manufactured with what's called a "right-hand thread". That means you turn it right to go into the wood, and you turn it left to bring it out of the wood. Now keep that 'right-hand thread' in the back of your mind, and we'll look at a vector cross-product. A cross-product is the new vector you get when you operate on two vectors that you already have. You obviously know the directions of the vectors that you already have, and you're asking "What is the direction of the new vector ?". Well, call the first two vectors 'A' and 'B'. If you do the cross-product (A x B), think of that right-handed screwthread rotating from the 'A' direction to the 'B' direction. What direction did the right-hand thread advance ? That's the direction of the cross-product ! Can you picture the three-dimensional Cartesian coordinate system ? Down at the origin, where the three axes come together, if you draw three little tiny vectors down on the three axes, you'll notice that ( x cross y = z ). This will help you a lot if you ever have to draw the axes properly on a blank sheet of paper. Notice that (B x A) goes in the opposite direction of (A x B), because when you turn a right-hand thread the other way, the screw advances oppositely. Another contributor may improve this answer by describing the "Right Hand Rule", which is another, maybe better, way to get the direction of the cross product. If he is not a total genius at descriptive language, it will confuse you.
Does the instantaneous speed ever equal the magnitude of its average velocity?
Yes. For a start, this happens when the object moves at a constant velocity. Also, if moving in a straight line, even if the object changes speed there must needs be a moment when its instantaneous speed is equal to its average speed - since it cannot change speed suddenly, it must do so gradually.
Is Heat a vector or a scalar quantity?
A vector
Can the component of a vector ever be greater than the magnitude of the vector?
No.
Does a car moving around the block drives at constant velocity?
It could move with a constant speed and not at constant velocity. Because the direction is ever changing. Speed is a scalar but velocity is a vector quantity which has direction aspect too.

Does vector the crocodile ever take his headphones off?
he never takes them off!!!!!
When can forces be added together?
forces can be added only when they both are going in the same direction as 2n + 2n = 4n of force in the same direction if they are 2 facing forces they would have had to be subtracted, which ever force is greater that will be the momentum of the force
Can the displacement vector for an object moving in two dimensions ever be longer than the length?
no
Can the magnitudes of the difference between two vector ever be greater than magnitude of either vector?
Yes. For example, if one vector has a length of 1 and points north, and the second vector has a length of 1 and points south, the difference (vector1 minus vector2) will have a length of 2 and point north.
Have you ever tried a carbonated beverage that comes in a can with CO2 for added fizziness"?
Yes, have you ever tried a fizzy drink in a can with added CO2?
What are the quantity unit symbol of derived units?
quantity units symbol area square meter m2 volume cubic meter m3
Can the magnitude of the difference between two vectors ever be greater than the magnitude of either vector?
Yes, the magnitude of the difference between two vectors can be greater than the magnitude of either vector. This can occur when the vectors are in opposite directions or have different magnitudes such that the resulting difference vector is longer than either of the original vectors.
Had the Australian constitution ever been added to?
reooow ! ;)
