Two boys hang by their hands from the same tree branch. The branch is straight, and grows out from the tree trunk at an angle of 30 degree above the horizontal. One boy, with a mass of 55.00 kg, is hanging 1.70 m along the branch from the tree trunk. The other boy, with a mass of 31.00 kg, is hanging 2.10 m from the tree trunk. What is the magnitude of the net torque exerted on the branch by the children? Assume that the axis is located where the branch joins the tree trunk and is perpendicular to the plane formed by the branch and the trunk.

(The objective paragraph should extend and mention the specific point to reach the goal) the report talking about system ventilation.. i need a paragraph about this about 4 lines Birefly

Problem- Cargo ships can cause a lot of air pollution.Solution-  to use nuclear powered ships since they hold a lot of energy and can travel for long distances. How it will work is that it will need a nuclear reactor at the bottom of the boat to heat up the water and then turn it to electricity to power the boat. The boat will be made out of graphene which is a tough material to avoid any leaks in the boat. It will also contain many control rods because nuclear power is so powerful that it can create to much energy to handle. With control rods, you can slow down this process and keep it in a controlled manner. Since cargo ships are already is the ocean, there will be no need for any extra materials to make it work. -Do you think this will work? Why/Why not?  -What do you think is wrong with it/ How can this be improved? Please send this to someone else I need to record 50 responses for a science project. Thank you!

How are stress and performance related?    A. Negatively linear: higher stress leads to lower performance   B. Curvilinear: the relationship is positive at lower level of stress but turns to negative as stress increases   C. No relationship   D. Positively linear: higher stress leads to higher performance
