It's the value set that determines if a result is statistically significant, or in other words, if it's not likely to have occurred simply due to chance. When probability value (p-value) is greater than alpha value, we fail to reject the null hypothesis.Probablity value is the probability of obtaining an answer equal to or more extreme than the observed value.Alpha value is the level of significance. What happens when probability value is greater than alpha value? When a zero vector is multiplied by a non-zero scalar, the Similarly, when a zero vector is subtracted from a vector, the When a zero vector is added to another vector, the result is The acceleration vector of a body in uniform motion is a zero The velocity vector of a stationary body is a zero vector. The displacement of a ball thrown up and received back by the The displacement of a stationary particle from time t to time tl The position vector of the origin of the coordinate axes is a The physical meaning of canīe understood from the following examples. It is important to note that we cannot take the above result toīe a number, the result has to be a vector and here lies the Multiplied by zero, the result is a zero vector. Zero vector or null vector is a vector which has zero magnitudeĪnd an arbitrary direction.
