Um pêndulo consiste em uma bola de massa m presa a um fio de comprimento L. A
ball is pulled until the wire forms an angle θo with a vertical. So it's dropped from
rest as shown in a figure. Neglect air resistance.
a) Show that the work done by the tension in the wire is zero.
b) Voltage is the only non-conservative force acting on the system. The fact does
work done by the voltage is null, implies in the conservation of energy
mechanics? Justify!
c) Determine a literal expression for the speed of the ball at the lowest point of the
trajectory as a function of the parameters θ and L given. Tip: make a diagram of
free body to facilitate.
d) Determine a literal expression for the module of the thread tension, at the most
down the trajectory according to the parameters θ and L given. .
Tip: Make a free-body diagram for ease

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
