Two men are pulling a tree in one direction while a third is chopping it down. The ropes make an angle of 30°. The first man pulls with a force of 430 N and the second man pulls with a force of 350 N. Use the parallelogram method (tail-to-tail method) to determine the resultant of their pulling forces.​

Natural forces that can alter ecosystems include seasons and climate changes. t or f

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
