Two objects 5kg and 7kg are attached to the ends of an inextensible string which passes over a frictionless pulley such that 5 kg is moving over a frictionless horizontal surface and the mass 7 kg is moving vertically downwards. Find the acceleration in the system and tension in the string.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).

Compare the patterns of the two waves shown in the image. which statement is true about these waves?

Aheavy boy and a lightweight girl are balanced on a massless seesaw. the boy moves backward, increasing his distance from the pivot point. what happens to the seesaw? it is impossible to predict without knowing additional information. the side the boy is sitting on will tilt downward. the side the girl is sitting on will tilt downward. nothing; the seesaw will remain balanced.
