Determine the frequency for the equation: 

y = 7.00sin(275t-6.0), 6.0 is in radians and 275 is in radians/sec

Round your answer to three decimal places

In lab tests on a 9.25‐cm cube of a certain material, a force of  1375 N directed at 8.50° to the cube (Fig. 10.4) causes the cube  to deform through an angle of 1.24°. What is the shear modulus  of the material?

Consider the balance between effective law enforcement and personal liberty. Which of these two principles outweighs the other? Are there any situations in which personal freedoms should be limited to ensure that police are able to prevent crime or successfully apprehend offenders? Why or why not?

Two properties of a reacting system at constant pressure and temperature can determine whether a process occur spontaneously: a) kinetic and potential energy change b) heat and work c) energy change and enthalpy change d) enthalpy change and entropy change

Why do we need to put a capacitor in a circuit? Explain your answer.

In a study with a sample mean of 14, a z of +2.0 is obtained. With a critical value of ± 1.96, the research team decides not to reject the idea that the sample represents a µ of 12.
a. Describe/draw the sampling distribution and indicate the relative locations of 𝑋̅, µ, the
computed z-score, and the two critical values. 
b. Is the conclusion given correct? Explain your answer. 
c. What population is this sample likely to represent? 

Before the invention of the electric refrigerator in 1913, people kept their food cool with blocks of ice in the home. (a) Calculate the work needed to lift a  block of ice a vertical distance of . (b) What  does the block have? (c) When the same block of ice is raised the same vertical distance by pushing it up a  ramp, only  of force is required. Calculate the work done to push the block up the  ramp. (d) What  does it have? (e) Draw a sketch of the ramp and determine the Mechanical Advantage of the ramp. 

Which of the statements is NOT correct? a) When AG for a reaction is negative, the reaction is spontaneous. b) When AG for a reaction is positive, the reaction is nonspontaneous. c) When AG for a reaction is zero, the system is at equilibrium. d) When AH for a reaction is negative, the reaction is never spontaneous. e) When AH for a reaction is very positive, the reaction is not expected to be spontaneous.

You have just completed a reliability improvement test for a newly designed component to be used within an aero engine that is manufactured by a big multinational company. This component went through 500 operational hours of reliability improvement testing and during this period there were 10 failures, and consequently 10 repairs/replacements/maintenances. These ten unscheduled  repairs/replacement/maintenances occurred at the following times: 0.6, 6.7, 19.2, 40.3, 56.2, 75, 197.1, 256.1, 491 and 496.6 hours. Apply a Power Law NHPP Model to this test data and to 3 decimal places, what is the unbiased estimate for the parameter b of this model?
