The increased number of small commuter planes in major airports has heightened concern over air safety. An eastern airport has recorded a monthly average of nine near misses on landings and takeoffs in the past 5 years. (Round your answers to three decimal places.)

(a) Find the probability that during a given month there are no near misses on landings and takeoffs at the airport . 

(b) Find the probability that during a given month there are three near misses.

(c) Find the probability that there are at least three near misses during a particular month.

A roller coaster as the bottom of a hill has a speed of 45.0 mph when it starts up a hill. The roller coaster moves with a constant deceleration of 0.75m/s^2 while coasting up the hill. Write equations for the car's position along the slope and its velocity as functions of time, assume x=0 at the bottom of the hill, where Vo=45.0 mph. Determine the maximum distance the roller coaster travels up the hill before it stops.

The roller coaster climb a hill then travel down to other side up another hill where ke greatest

A) top of the hill

B)bottom

C)halfway

D)top of second hill

Answer:

Chlorous acid, HClO₂, has a dissociation constant of K_a = 1.20 x 10^–2 .

Calculate the degree of dissociation for a 0.0766m solution of this acid:

(a) using the Debye–Hückel limiting law

(b) assuming that the mean ionic activity coefficient is one.

A weak acid has a dissociation constant Ka = 1.20 x 10 ^ -2.Calculate the degree of dissociation for 0.0825 m solution of thisacid using Debye - Huckel limiting law.

Answer should be 37%.

Thank you!
