Aunit cell has a lattice constant a, where a is the length of a single side of the unit cell. draw a cube and derive the length of the diagonal from one top corner of the unit cell to the bottom far corner (ie. the largest distance between corners in a 3-d cube)

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

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.
