assignment: seismic waves research current events exploration

for this lesson's graded assignment, you will do research on the internet to learn more about the role seismic waves play in earthquakes and tsunamis. your essay will address one of the following questions:

• how does an underwater earthquake cause a tsunami?
• why do some earthquakes cause more damage than others?

here is a website and some keyword search terms to you get started.

usgs earthquakes

keywords search terms: earthquake formation, p wave, s wave, tsunami, earthquake travel, analyzing earthquakes

your essay should do the following things:
• discuss how the different types of waves are formed and describe how the waves travel
• explain how scientists use waves to track and analyze earthquakes
• cover recent events involving earthquakes and/or tsunamis that illustrate the points made in your explanation

the essay should be about 350-450 words, which is 1-1.5 typed pages, double-spaced, using 12-pt. font. check the rubric to review how you will be graded for this assignment.

The 20@kg wheel has a radius of gyration about its center g of kg = 300 mm. when it is subjected to a couple moment of m = 50 n # m, it rolls without slipping. determine the angular velocity of the wheel after its mass center g has traveled through a distance of sg = 20 m, starting from rest.

Aroll in a paper machine is powered by a separately excited dc machine. operating point 1 (under load): the roll typically operates at 764 rpm and must provide 301 nm of torque to oppose the load of the paper. the armature voltage is 230v for this operating point operating point 2 (no load): when the load is removed the speed of the roll increases to 900 rpm (the field characteristics are unchanged) la ea dev m (a) calculate the maximum torque (units of nm) that the motor can supply with this applied voltage (b) calculate the value of the armature resistance, ra (in ohms) (c) at operating point 1 (loaded condition), the field current, i, and the total input power (armature field), are measured to be to be 10 a and 28,600 w respectively. use this information to calculate the value of the field resistance, rf (in ohms). (d) (d) at operating point 1 (loaded condition), calculate the motor efficiency. express your answer as a percent to at least 2 significant digits. (d) if the field voltage is reduced by 1/2, calculate the new stall torque (in nm) of the motor (f). if the field voltage is reduced by 1/2, calculate the new no-load speed (in rad/sec)

Acar moves a distance of 50.0 km west, followed by a distance of 64.9 km north what was the magnitude of the displacement of the car, in units of kilometers?
