Answer 2

Answer:

a) Long

Explanation:

to open a bit using a spanner a larger momentum is required.

this momentum is equal to product of force and perpendicular length of application of force.

momentum = force * distance

Now to open up a bit with the application of small force thr handle of the spanner needs to be long to create a larger momentum.
