A simple pendulum is 30.0 inches long and has mass at the end that weighs 5.00 pounds on Earth. Calculate the frequency of the pendulum if it is transported to the surface of Mars, where the acceleration due to gravity is 3.73 m/s2.  

Students are randomly assigned to one of nine teams in a class.  They are equally likely to be assigned to any team.   X is the team to which a student is assigned; x = 1, 2, 3, 4, 5, 6, 7, 8, 9.  Determine the population standard deviation of X. This question is copywritten by Arizona State University and Linda Chattin.  It may not be posted to any website, may not be texted to anyone, and may not be screenshot or photographed.  If your answer is non-integer, express it to three decimal places.

A public address speaker is placed against a wall and therefore emits all its sound energy hemispherically. When a test tone is played through the speaker, it produces  an intensity level of 140 dB (ouch!) at a distance of 1.00 meter from the speaker.  a) What is the sound power emitted by the speaker? b) At what distance from the speaker would the intensity level be 120 dB?

The net weight in pounds of a packaged chemical herbicide has the following CDF:                         F(x)      = 0                   for x < 49.7 lbs.                                     =  

Two trains are approaching each other on parallel tracks. Train 777 is moving South at 77.7 MPH and train 666 is moving North at 66.6 MPH. The conductor on train 777 blows his horn and hears a frequency of 440 Hz. What frequency does the conductor on train 666 hear? Assume the speed of sound is 345 m/s. 

A spring with an unstretched length of 40.0 inches is hung from the ceiling. A 10.0 lb weight is then hung from the bottom of the spring and stretches it downward by 4.00 inches. The weight is then pulled a further 6.00 inches downward and released from rest. Calculate: a) the spring constant of the spring b) the frequency of the resulting oscillations c) the maximum velocity of the weight as it bounces up and down
