Barton conducts an experiment using three metallic bars that might be magnets. the bars are labeled a, b, and c. the ends of each bar are numbered 1 or 2. 1a2 | 1b2 | 1c2 he places the end of one bar close to an end of a second bar and records his results in the table shown. based on the data, which prediction should he expect to occur? a) a2 repels b1. b) c2 attracts b2. c) b1 repels c1. d) a1 attracts c2.

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

Your science teacher brings in a speaker to talk to your class about climate change. during the session, students ask a few questions. which questions are related to the current evidence on climate change
