Please solve and answer the 3 questions below. I’ve attached images on the actual word problems. Only need the answers. Thank you in advance. 

1) The weight of the bucket-seat and the operator is 800N. What is the tension on the rope? Select the correct answer. Please see image attached.

2) At equilibrium, what is tension Tb if the weight w= 100N? Please see image attached.

3) What is the tension on the rope if the weight of the person at the center of the rope is 1000N?
