g A planar loop of wire (i. e. the object would lie flat on a page) with areaAis oriented so it is parallel tothex−yplane. It is released from rest at a heightz=h >0 and accelerated downwards with constantaccelerationa. The loop has resistanceRand is exposed to a magnetic field~B= (h−z)2ˆz. a) Find how much current runs though the wire, include the direction when seen looking down from abovethe loop. b) How much energy was consumed by the loop since being released when it reaches the ground atz= 0

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?

What is the momentum of a 2 kg object moving at 15 meters per second

Which are advantages of renewable resources? check all that apply. renewable energy supplies are completely reliable everywhere. some renewable resources will never be used up. little or no waste is produced by renewable resource plants. electricity can be generated in large quantities. many renewable energy facilities have lower operating costs.
