Consider a stationary solution of the Schrodinger Equation with positive energy E for a particle with mass m in the following one-dimensional potential: V (x) = 0 for |x| > a and V (x) = −V0 for |x| ≤ a with V0 > 0. (a) Calculate the transmission and reflection probabilities. (b) Show that the transmission probability is unity for some values of the energy.

Suppose that you are designing a parachute so that the terminal velocity using the parachute will be the same as the velocity at the end of a normal (frictionless) jump from a height of 2.80 m. If the parachute exerts a drag force of - b v where v is in meters per second and if the parachute is designed for an 70.0 kg person, what is b?

1. Consider a charge of -1 nC at (-1,0) m, and a charge of +1 nC at (1,0). Calculate the electric potential everywhere in the plane.

2. For the same geometry as in the first problem, calculate the electric field everywhere, using -?V =E. In 2 dimensions, ?V= (?subxV, ?subyV) = ?subxV x^ + ?suby Vy^

A 15.2% (m/v) solution of sodium chloride (NaCl) is used to prepare 25.0 L of a physiological saline solution with a concentration of 0.154 M NaCl. What volume of the 15.2% (m/V) solution of sodium chloride would be required to make 25.0 L of the physiological saline solution ( 0.154 M NaCl) ?

For the following reaction: NiO2(s) + 4 H+(aq) + 2 Ag(s) → Ni2+(aq) + 2 H2O(l) + 2 Ag+(aq) script E° = 2.48 V Calculate the pH of the solution if script E = 2.32 V and [Ag+] = [Ni2+] = 0.012 M. Use the Standard Reduction Table.

a.A method that accepts no parameters and returns the length of the name, i.e., the sum of the lengths of the three parts of the name.

b.A method that accepts no parameters and returns a String consisting of the three initials IN UPPERCASE.

c.A method that accepts an integer n and returns the nth character in the full three part name.

d.A method that accepts no parameters and returns a String consisting of the last name followed by a comma followed by the first name followed by the middle name. Remember to put spaces between the names.

e.A method that accepts a String and returns true if the String is equal to the first name (use the equals method in the String class!). This is not quite the proper way to define an equals method, as we will learn later.

f.A method that accepts a Name object and returns true if the three parts of the name object are the same as the three parts of “this” Name object.

Create a class called NameDriverwhich contains a main method. Inside the main method, instantiate a Name object using your name and test your methods to make sure they work.Does it work for all name

write a complete program that prompts the user to enter their first name, middle name, and last name (separately). print out thier name and initials, exactly as shown:

your name is: John Paul Chavez

your initials are: J. P. C.

use string method chartAt() to extract the first (zero-th) character from a name(the name is a string type): username.charAt(0).

CO2(g) + C(s) = 2 CO(g) a) Using the Bouduard reaction, calculate gas composition in a furnace under 1 atm total pressure and 1100 K. b) Under the same furnace conditions, is it possible to reduce VO to V by CO? ( VO + CO = V + CO2 ) C(s) + O2(g) = CO2(g) o GT = - 394100 – 0.84 T J/mol C(s) + ½ O2(g) = CO(g) o GT = - 111700 – 87.65 T J/mol V(s) + ½ O2(g) = VO (s) o GT = - 424700 + 80.04 T J/mol
