ISTime is a vector?
Time is not a vector quantity. A vector quantity describes the magnitude and direction of an object.
What is time vector or scalar?
Time is scalar
What does the head of a vector arrow represent?
The head of a vector arrow represent the time traveled
Is time a scalar or a vector?
Scalar
Is power a vector quantity or a scalar quantity?
vector, power= work/time and work= force * distance, force is vector.
ISTime is a vector?
Time is not a vector quantity. A vector quantity describes the magnitude and direction of an object.
Is the size of the vector is fixed at the time of compilation?
The size of a vector is not fixed at time of compilation as it can be altered by events that can be written into code. For example, a vector can have a new Node pushed to the back when something happens, altering the size of the vector during run-time.
What is time vector or scalar?
Time is scalar
What does the head of a vector arrow represent?
The head of a vector arrow represent the time traveled
What is the name of a vector quantity that is the rate at which velocity changes over time?
The name of the vector quantity that represents the rate at which velocity changes over time is acceleration.
Is time a vector quanititie?
No, time is assumed to be a scalar.
How is time a vector quantity?
Time is not a vector quantity, it is a scalar quantity. A vector quantity has both magnitude and direction, while time only has magnitude (such as hours, seconds, etc.) and does not have a specific direction associated with it.
Is time a scalar or a vector?
Scalar
What is the physical significance of null vectors?
Zero vector or null vector is a vector which has zero magnitude and an arbitrary direction. It is represented by . If a vector is multiplied by zero, the result is a zero vector. It is important to note that we cannot take the above result to be a number, the result has to be a vector and here lies the importance of the zero or null vector. The physical meaning of can be understood from the following examples. The position vector of the origin of the coordinate axes is a zero vector. The displacement of a stationary particle from time t to time tl is zero. The displacement of a ball thrown up and received back by the thrower is a zero vector. The velocity vector of a stationary body is a zero vector. The acceleration vector of a body in uniform motion is a zero vector. When a zero vector is added to another vector , the result is the vector only. Similarly, when a zero vector is subtracted from a vector , the result is the vector . When a zero vector is multiplied by a non-zero scalar, the result is a zero vector.
Is power a vector quantity or a scalar quantity?
vector, power= work/time and work= force * distance, force is vector.
Which physical quantity is obtained when acceleration is differentiated with respect to time is it a scalar or vector or tensor?
For differentiation, you have to divide a vector by a scalar. Therefore, you should get a vector.
How could you represent the speed and direction of a car if you able to measure its position vs time?
If s is the vector which denoted the position at time t, then the vector ds/dt is the required vector. Its magnitude is the car's speed and its direction is the car's.
