(double points) a worker applied 27 newtons to a lever with a length of 4 meters that rotated around a hinge. what was the torque?

The torque was 108 N m

Explanation:

Torque is the cross product between the vector position where the force is applied with respect the axis of rotation and the force applied:

The magnitude is:

If the force is applied on an extreme of the lever, the hinge is in the other extreme and the applied force is perpendicular to the lever:

, ,

So:

the part of the wave he is travelling on is the crest

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
