The range of human hearing extends from approximately 20 Hz to 20,000 Hz. Find the wavelengths of these extremes at a temperature of 27°C
The Need for Security
Why is coding vital for security? Provide instances where HIPPA, National Security, Bank/Heath industries must have stringent coding practices. Explain why. If possible, provide a small piece of code (Java or Python snippet) that illustrates this.
two parallels wires, wire P and Q which carries a current of 30A and 50A, respectively in the same direction.The wires are placed 1.25 mm apart in a vacuum.
a) Calculate the magnetic force per unit length on wire P.
b) Determine the position x from wire P in between the wires where the magnetic field is zero.

A 2-hour movie runs continuously at a local theater. You leave for the theater without first c checkingthe show times. Use an appropriate uniform density function to find the probability that you will arrive at the theater within 10 minutes of (before or after) the start of the film.
An organic compound is known to be nonvolatile and non electrolyte. A 0.35g sample is dissolved in water and diluted to 150mL. The osmotic pressure is measured as 0.04 atm at 250C. The approximate mass number for this compound is 1400g/mol. From the data provided in this problem and knowing that the density Of the solution is 1.00g/mL
a. Calculate the freezing point of the solutions.
b. Determine if the freezing point change would be a good way to determine the molecular mass of the compound.
c. Would the boiling point change be a better determining factor than the freezing point change?
