Askier is pulled by a tow rope up a frictionless ski slope that makes an angle of 7.6° with the horizontal. the rope moves parallel to the slope with a constant speed of 1.2 m/s. the force of the rope does 960 j of work on the skier as the skier moves a distance of 7.9 m up the incline. (a) if the rope moved with a constant speed of 2.7 m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 7.9 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) 1.2 m/s and (c) 2.7 m/s?

a and b sometimes have a positive value

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
