For this exercise, you are going to create 2 instance variables and the structure of the constructor for the DNA class. DNA objects contain two strings, a rsid and a genotype. Create the instance variables with the appropriate privacy settings. Then create the structure of the constructor to take two parameters to match the instance variables. Make sure you set the privacy settings on the constructor correctly. (You do not need to complete the constructor). Note: Because there is no main method, your code will not execute (that’s ok). Use the autograder to verify that you have the correct code.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

With increases in magnification, which of the following occur? a. the field of view decreases. b. the ambient illumination decreases. c. the larger parts can be measured. d. the eyepiece must be raised.

Tom is having a problem with his washing machine. he notices that the machine vibrates violently at a frequency of 1500 rpm due to an unknown rotating unbalance. the machine is mounted on 4 springs each having a stiffness of 10 kn/m. tom wishes to add an undamped vibration absorber attached by a spring under the machine the machine working frequency ranges between 800 rpm to 2000 rpm and its total mass while loaded is assumed to be 80 kg a) what should be the mass of the absorber added to the machine so that the natural frequency falls outside the working range? b) after a first trial of an absorber using a mass of 35 kg, the amplitude of the oscillation was found to be 10 cm. what is the value of the rotating unbalance? c) using me-3.5 kg. m, find the optimal absorber (by minimizing its mass). what would be the amplitude of the oscillation of the absorber?
