I tutor in math, but I'm not sure how to do this type of inequality. When I went to school, inequalities were not stressed much.

I need to know how many chromatids per chromosome there are for the stages G1, S, G2, prophase, metaphase, anaphase, and telophase.

I think its
G1=1,
S=2,
G2=2,
prophase=2,
metaphase=2,
anaphase=1
telophase=2

Am I correct in my thinking or do I have the whole thing messed up or just some of it?

Two ice skaters, with masses of 50 kg and 75 kg, are at the center of a 60 m diameter circular rink. The skaters push off against each other and glide to opposite edges of the rink. If the heavier skater reaches the edge in 14 s, how long does the lighter skater take to reach the edge?

I have no idea why a cannot get this one. Here's what I am doing:

d = Vit + 1/2at^2

30=1/2(a)(14)^2
a = 0.306 m/s^2 <--acceleration of heavier skater


ma = ma
75(0.306) = 50a
a = 0.459 m/s <--acceleration of lighter skater

30 = 1/2(0.459)t^2
t = 11.430 sec

^That answer appears to be incorrect. Any suggestions?


Thanks

In a home laundry drier, a cylindrical tub containing wet clothes rotates steadily about a horizontal axis, as in Figure P7.63. The clothes are made to tumble so that they will dry uniformly. The rate of rotation of the smooth-walled tub is chosen so that a small piece of cloth loses contact with the tub when the cloth is at an angle of 68.0° above the horizontal. If the radius of the tub is 0.385 m, what rate of revolution is needed?

i work in security engineering position for really sometimes, but there is something amazingly very basic i am still in doubt
we pretty often have our own information system with built in security, we follow the industrial best practices to ensure the security of these propeteriey system, but i have a doubt sin ce the system is private, the hacker would be hard if possible to gain the system, analyse and find vulnerability, but that is practically not easy, and we waste really much on all the info system we developed, so there are the reverse engineering tool that can reveal the original structure of the program they want to hack, including the info for commentation, but what are they and how they do it, can anybody give me a couple of tips or tools
