8. A ball is spinning around at the end of a cable with an initial tangential speed of 5 ft/s and a distance from the center of the table of 3 ft (assume the hole in the middle is negligibly small). The end of the rope is then pulled down through the table at 1.5 ft/s. Calculate the distance from the center of the table to the ball when the ball's total speed is 10 ft/s. 5 ft/s 1.5 ft/s

How does an increase in ploidy contribute to evolution? Sterile allopolyploids commonly pass down novel genes that evolve. All copies of the genes found in polyploids gain a new function. Speciation results from a fusion of haploid gametes. One copy of a gene retains its function, whereas the other gene copy develops a new function.

A long, thin metal rod is given a linear charge density of βˆ’6.0 πœ‡πΆ. π‘šβˆ’1 before it’s placed in a sheath with positive linear charge density +6.0 πœ‡πΆ. π‘šβˆ’1 (with a thin air gap so that no contact is made). The rod has radius 1.0 cm, and the sheath has a radius of 1.5 cm to the inner wall and a cylindrical shell of thickness 0.50 cm. a) If we placed a negative charge at the location at point P, would it feel a force due to the charged cylinders? Why or why not? If it would, in which direction does the force point? b) For a cylindrical Gaussian surface of radius 1.25 cm centred on the metal
