Answer:

Acceleration is a vector quantity.

Explanation:

The quantities that have both magnitude and direction are called vector quantities. Vector quantities follows the law of vector addition, subtraction, division, multiplication.

Out of the given options acceleration is a vector quantity. It has both magnitude and direction.

On the other hand, mass, speed and volume is a scalar quantity. These quantities have only magnitude.

Hence, the correct option is (A) "acceleration".

You push very hard on a heavy desk, trying to move it. You do work on the desk:

frozen [14]

Answer:

Explanation:

We know that work done is given by

$W=F.d=Fdcos\Theta$

So there are two case in which work done is zero

First case is that when force and displacement are perpendicular to each other

And other case is that when there is no displacement

So for work to be done there must have displacement, if there is no displacement then there is no work done

So option (c) will be the correct option
