14. In what way is a screw similar to an inclined plane? O A screw is an inclined plane wrapped around a cylinder.
O A screw and an inclined plane both have threads.
O A screw is put in place with a screwdriver, which is a wedge.

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
