Agrasshopper makes four jumps. the displacement vectors are (1) 38.0 cm, due west; (2) 27.0 cm, 42.0° south of west; (3) 20.0 cm, 66.0° south of east; and (4) 23.0 cm, 77.0° north of east. find (a) the magnitude and (b) direction of the resultant displacement. express the direction as a positive angle with respect to due west.

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

Did anyone do 1.06 lab: cloud formation i need with it i go to k12 lavcame i need to get it done quick

There are multiple tuning forks present in the room, and annie strikes one with a natural frequency of 400 hz. which of these other tuning forks will begin to vibrate through resonance and make the sound louder? a 200 hz tuning fork a 400 hz tuning fork a 800 hz tuning fork a 1600 hz tuning fork
