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.​

Aphysical change is a change in the size, shape,, or stafe of matter true or false

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
