the common metallic elements have been invetigated for their relative reactivities and have been arranged into what is called electromotive series. Explain the series in terms of choosing the suitable electrode in setting up an electrochemical series.

How would you set up a system of linear equations to find out how many packages of 8 and 12 you would have to buy to have no left?

**Physics**

A object-spring system oscillates with an amplitude of 3.8 cm. If the spring constant is 210 N/m and object has a mass of 0.50 kg, find the maximum speed of the object. I already have the mechanical energy of the system. How do I find the maximum speed?
