67.

Identify the vector quantity from the following

 [A]. Heat [B]. Angular momentum [C]. Time [D]. Work

Explanation:

No answer description available for this question.

 Tin said: (Feb 22, 2012) It is only angular momentum which has both direction and magnitude.

 Sorabh said: (Jan 19, 2014) Angular momentum = M.I * Angular velocity and angular velocity is vector quantity.

 Dami said: (Aug 20, 2015) Heat is scalar but temperature is vector.

 Fon. L said: (Sep 25, 2015) Temperature is not a vector.

 Asha said: (Oct 7, 2015) Why not work?

 Kavya said: (Apr 29, 2016) Work is defined as a dot product (or scalar product) of force and displacement, both of which are vectors. A scalar product of two vectors gives a scalar result. dW= Fs cos theta Where F & s are the magnitude of the vectors. (Theta being the angle between the vectors).

 Rks Orissa said: (Sep 7, 2016) Someone please clear me to know easily about the scalar and vector quantities.

 Malik Asim said: (Aug 24, 2018) If a quantity can have magnitude and direction to determine as well as is called a vector. If a quantity can have magnitude and unit to determine As well as is called scalar. On another hand. If two quantities contain the dot product between them then the 3rd. The quantity which is determined by these two is scaler and. If contain cross product then it is called a vector.
