The highest recorded waterfall in the world is found at angel falls in venezuela. its longest single waterfall has a height of 807 m. if water at the top of the falls is at 15.0 °c, what is the maximum temperature of the water at the bottom of the falls? assume all the kinetic energy of the water as it reaches the bottom goes into raising the water’s temperature

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?

Arrange the images in order to show how lake-effect snow occurs.

The force it would take to accelerate an 900-kg car at the rate of 6m/s2
