This question involves the concepts of torque, applied force, and force arm.
The net torque about the axle will be "0.94 N.m clockwise".
The net torque can simply be found by adding the torques produced by every force about the axle, that is at some perpendicular distance from the axle and whose line of action does not touch with the center point. We will take the clockwise direction as negative here, and the counter-clockwise direction as positive. The torque due to a force can simply be given as the product of the force and the perpendicular distance between center point and force, also known as force arm.
T = -3 N.m + 1 N.m + 1.06 N.m
<u>T = -0.94 N.m</u> (negative sign shows <u>clockwise direction</u>)

A hypothesis is an educated guess. It refers to a theory you have based on some sort of evidence you collected or noticed. It is not fact and can sometimes be proven wrong. A law would refer to a scientific fact that has been proven correct and is a fact about the subject.

Answer:
He can return to the spacecraft by sacrificing some of the tools employing the principle of conservation of momentum.
Explanation:
By carefully evaluating his direction back to the ship, the astronaut can throw some of his tools in the opposite direction to that. On throwing those tools of a certain mass, they travel at a certain velocity giving him velocity in the form of recoil in the opposite direction of the velocity of the tools. This is same as a gun and bullet recoil momentum conservation. It is also the principle on which the operational principles of their maneuvering unit is designed.
