What are the effects of refrigerator and air conditioner on ozone layer?
CFCs, and are known ozone depleters. See the link below for what their effects are.: * Refrigerant R-10 is CCl4. * Refrigerant R-11 is CCl3F. * Refrigerant R-12 is CCl2F2. * Refrigerant R-13 is CClF3. HCFCs, and are known ozone depleters but with lowered suvivability to reach the ozone layer. See the link below for what its effects are. * Refrigerant R-22 is HCClF2. * Refrigerant R-40 is CH3Cl. It is responsible for ~17% of chlorine-assisted ozone destruction in the statosphere. It is today primarily produced by plants, and the combustion of organic waste materials, since its use in industry was stopped some time ago. CFCs inclusive of HCFCs, are ~82% of the chlorine currently found in the stratosphere Some refrigerants that do not contain chlorine or bromine are: R-14, R-23, R-32, R-41, R-50, R-116, R-125, R-E125, R-134, R-134a, R-E134, R-143, R-143a, R-143m, R-E143a, R-152, R-152a, R-161, R-170, R-218, R-227ca, R-227ca2, R-227ea, R-227me, R-236cb, R-236ea, R-236fa, R-236me, R-FE-36, R-245ca, R-245cb, R-245ea, R-245eb, R-245fa, R-245mc, R-245mf, R-245qc, R-254cb, R-254pc, R-263, R-272, R-281, R-290, R-C318, R-3-1-10, R-347mcc, R-347mmy, R-365mfc, a few of the blends between R-400 and R-600, R-600, R-600a, R-601, R-601a, R-610, R-611, R-630, R-631, R-702, R-704, R-717, R-718, R-720, R-728, R-732, R-740, R-744, R-744A, R-764, R-784, R-1114, R-1132, R-1141, R-1150, R-1216, R-1270 This list includes chemicals that are so stable that they also can accumulate over decades as CFCs did, and yet new problems may result from their use and/or release into the environment. Others of them are fuels (so are flammable), components of natural gas, and may not accumulate, but can contribute to ozone pollution as a VOC.

What is the 118th sequence in y-r-r-y-r-r-y-r-r-y-r-r-y-r-r?
It is y. Every third letter is r, immediately followed by y, and since 117 is divisible by 3, it is r. Therefore, 118 is y.

What did Turtle from the westing game do to anyone who touched her braid?
Well, honey, Turtle from "The Westing Game" wasn't messing around. If anyone dared to touch her braid without permission, she would straight-up bite them. Yep, you heard me right. Turtle wasn't about to let anyone mess with her hair or her personal space. So, hands off the braid unless you want a surprise nibble!
Prove that nCr plus nCr minus 1 equals n plus 1Cr?
nCr + nCr-1 = n!/[r!(n-r)!] + n!/[(r-1)!(n-r+1)!] = n!/[(r-1)!(n-r)!]*{1/r + 1/n-r+1} = n!/[(r-1)!(n-r)!]*{[(n-r+1) + r]/[r*(n-r+1)]} = n!/[(r-1)!(n-r)!]*{(n+1)/r*(n-r+1)]} = (n+1)!/[r!(n+1-r)!] = n+1Cr
