1) Inhabitants of the fifth planet in a solar system on the other side of the Galaxy measure distance in units called "ladoladelums" and time in units called "forevers". They observe that, a) all the planets in their solar system are much smaller than their Sun,

b) all planets have nearly circular orbits,

c)the fourth planet is about 32 ladoladelums from their Sun and completes one revolution in about 47 forevers, and

d) the third planet completes one revolution in 13 forevers.

Question: About how far from their Sun does the third planet lie?

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?

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.
