Two large books are stacked on top of each other on a table(Figure 3). The mass of each book is 6.5 kg. Given that the coefficient of static friction between the bottom book and the table is 0.15, what is the lowest the coefficient of static friction between the books can be in order to apply force and move both books?

the device is called “ rocket engine”

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

less than one you can't create energy
