Given, gas Y effuses half as fast as O2.
The molar mass of gas Y is calculated by using Graham's law.
(R1R2)2=M2M1
where,
R1 and R2 =rates of diffusion
M1= molar mass of O2
M2= = molar mass of gas Y
The molar mass of gas Y is
(21)2=M232
41=M232
M2=32×4
=128 gmol
Molar mass of gas Y=128 gmol

In Figure, a stationary block explodes into two pieces and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 2.6 kg, encounters a coefficient of kinetic friction μL=0.40 and slides to a stop in distance deal = 0.15 m. Piece R encounters a coefficient of kinetic friction μR=0.50 and slides to a stop in distanced R=0.30 m. What was the mass of the original block?

Jones figures that the total number of thousands of miles that a used auto can be driven before it would need to be junked is an exponential random variable with parameter 120.
Smith has a used car that he claims has been driven only 10,000 miles.
If Jones purchases the car, what is the probability that she would get at least 20,000 additional miles out of it?
Repeat under the assumption that the lifetime mileage of the car is not exponentially distributed but rather is (in thousands of miles) uniformly distributed over (0, 40).
