Of the following which is not a scalar quantity?
(a) time (b) momentum (c) volume (d) density
Answers
The one which is not a scaler quantity is "Momentum".
The correct answer to the question is momentum.
EXPLANATION:
Before coming into any conclusion, first we have to understand scalar and vector quantity.
A vector quantity is a physical quantity which have magnitude as well as direction for its complete specification and it is in accordance with parallelogram law of vector addition.
A scalar quantity is a physical quantity which require only magnitude for its complete specification.
As per the options given in the question, the momentum is not a scalar quantity.
The momentum of a body is defined as the product of mass with velocity .
Mathematically momentum p = mv
Here, v is the velocity of the body.
We know that velocity is a vector quantity and mass is scalar quantity.
Hence, momentum of a body is a vector quantity as it is the scalar multiplication of velocity.
