Is it possible to calculate the torque acting on a rigid object without specifying an axis of rotation? Yes No (b) Is the torque independent of the location of the axis of rotation?

a) No

b) yes

Explanation:

a) No, we need distance from center of rotation which is to exist on axis of rotation !

b) Yes

the answer to both questions is no.

Explanation:

The vector of a torque is oriented in a 3D Euclidean space. Its orientation point is relative to the origin in a specific coordinate system. If the coordinate system is removed, only the vector part would be had. This means that the direction and magnitude of the vector could not be calculated. This means that the vector cannot be found without a specific origin.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
