Answer 1

Answer:

Displacement is a vector quantity

Answer 2

Answer - Speed is not a vector quantity whereas all the others are ..

Hence , Option D is th correct answer .

Additional Information -

• Momentum

Momentum refers to the quantity of motion experienced by a body .

It is represented by P and is equal to MV .

Mass is a scalar quantity whereas Velocity is a vector quantity .

The product of a vector and a scalar quantity is always vector .

Hence , Momentum Is a vector quantity .

• Displacement

This refers to the shortest dinstance between two points and is a vector quantity .

• Torque -

Torque is the product of a force applied on an object and it's position vector.

Both the force and the position vector are vector quantities and hence, torque is a vector quantity.
