An airliner lands with a speed of 47.0 m/s.
Each wheel of the plane has a radius of 1.25 m and a moment of inertia of 110 kg*m^2. At touchdown the wheels begin to spin under the action of friction.
Each wheel supports a weight of 1.40X10^4 N, and the wheels attain their angular speed in 0.53 s while rolling without slipping.

QUESTION:
What is the coefficient of kinetic friction between the wheels and the runway? Assume that the speed of the plane is constant.

take out the space between the / and the D and don't put the three dots at the end, if you copy that and paste hopefully it'll get you there

given: segment QO is congruent to segment QN
segment NM is congruent to segment OP

PROVE: triangle QMP is isoscles

starting from the left corner, the letters are M, N, O, and P; Q is all the way at the bottom

thanks!

If atheists don't believe a greater source of power created everything what do they believe. What happened before the big bang, was there once nothing? How was the first thing created.

The ratio of men to women at a certain company is 5 to 3. How many employees does the company have if there are 54 female employees?

men = 5
women = 3
54 divided by 3 = 18
18 * 54 = 972

OR
18 * 5 = 90
or neither?
help...

If the expression:

8x+1/3x+3


is to make sense, the values that x can take must be restricted. State the restriction on x .

(8*x+1)/(3*(3*x/3+3/3))
(8*x+1)/(3*(x+1))
Solving is not the answer, so I am confused how to
state the restriction

1)what volume of calcium chloride holds a pound of ammonia? (i really need a graph chart covering temprature /pressure)

2) does the electrical resistance of calcium chlride change as it becomes satureted with ammonia?

i really need some help with this....i have been unable to find any temp/pressure graph charts dealing with ammonia saturated calcium chloride. im in the process of trying to build a solar powered air conditioner with a bank of generator/absorber cells,an air cooled tower condensor, a large liquid ammonia reciever, an ammonia evaporator/glycol heat exchanger, and finally a gravity fed glycol/room ait heat exchanger.

yes, i am fammiliar with the dangerous pressures that will be generated. i know that ammonia is nasty stuff, and i understand basic thermodynamics (i install and fix air conditioners for a living)

i just need help with the chemistry end of the thing.

with gratitude,
Possum

ps.....please feel free to IM or email me (in my bio)
