Answer:
With the addition of the pipe we have a greater torque.
Explanation:
We need to complete the description of the problem, searchin in internet we have:
"Sometimes, even with a wrench, one cannot loosen a nut that is frozen tightly to a bolt. It is often possible to loosen the nut by slipping one end of a long pipe over the wrench handle and pushing at the other end of the pipe. With the aid of the pipe, does the applied force produce a smaller torque, a greater torque, or the same torque on the nut?"
With the addition of the pipe we have a greater torque, as it increases the distance or radius of torque.
We know that torque is defined, as the product of force by distance, in this way we have:
T = F * d
where:
T = torque [N*m]
F = force [N]
d = distance [m]
We can see in the above equation, that increasing the distance increases torque proportionally.
Newtons law of gravitation is called the universal law of gravitation because it is applicable for all masses at all distances, independent of the medium.
I believe your answer should be C. Speed.
