There is a small scratch on a disco record located 14.5 cm from the center. When played, the scratch makes the record skip 30 times each minute (i. e., the scratch passes under the record player needle 30 times per minute). What is the linear speed of the scratch as it turns

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.
