Two boys pull a tree stump with ropes. The ropes are at an angle of 90 degrees to each other. One boy pulls with a force of 80N and the other boy pulls with a force of 60N. Find, by a suitable scale drawing, the resultant force of the ropes on the tree stump.

Nitrogen (n2) undergoes an internally reversible process from 6 bar, 247°c during which pν1.2 = constant. the initial volume is 0.1 m3 and the work for the process is 121.14 kj. assuming ideal gas behavior, and neglecting kinetic and potential energy effects, determine heat transfer, in kj, and the entropy change, in kj/s. show the process on a t-s diagram.

If the specific heat of a metal is 0.850 j/g °c, what is its atomic weight?
