Determine the velocity of the 60kg block A, if the two blocks are released from rest, and the 40kg block B moves 2m up the incline. Do this problem for the following three cases:1.There is no friction. 2.The coefficients of static and kinetic friction between the blocks and incline are 0.13.The coefficients of static and kinetic friction between the blocks and incline are 1.0

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?

What is the length x of the side of the triangle below? (hint: use the cosine function)

Avehicle has an oil leak that is causing the entire oil pan to be wet, but inspection reveals no exact source after cleaning off the oil residue. technician a says to install a fluorescent dye in the crankcase and operate the engine, then re-inspect for leaks with a special light (black light). technician b says the oil leak may be coming from a source at the top of the engine, such as a valve cover gasket. who is correct?
