All A seismograph is an instrument that is used to measure seismic waves. When analyzing the results from the
seismograph, what does it mean if the amplitude on the
graph is small?

A: The earthquake in that location was strong,

B: The smaller the selsmic waves, the more destructive the earthquake is.

C: The earthquake in that location was not that strong,

D:That location was close to the epicenter.

Gordon is going for a run through the park, but it is cold outside. the low outside temperature could affect his personal safety.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
