Two boys want to move the chair by applying two forces perpendicular to each other, of module F1 = 65 N and F2 = 83 N. Another boy applies a force F3 to the chair which opposes the movement and keeps it steady. Calculate the angle of inclination of the resultant of F1 and F2. What is the form, direction and direction of F3?

B) as the temperature increases, the kinetic energy of the particles increases.|-/

"induction" is the process of charging an object without touching it.hope my answer has you : )

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
