Question

since work will remain the same, a decrease in force requires
a decrease in distance.
no other changes.
distance to remain the same.
an increase in distance.
question #5
a machine is a device that makes
decreases work
less work.
more work
work easier

Explanation:

1. Recall the work - formula $W = F\times d$ (where $W$ is work, $F$ is force, and $d$ is distance). If $W$ is constant and $F$ decreases, then according to the formula, $d$ must increase to keep $W$ the same.
2. A machine is a device that changes the way work is done. It doesn't change the amount of work done (assuming no energy losses), but it makes work easier by changing force, distance, or the direction of the force.

Answer:

1. An increase in distance
2. Work easier
