Using the latitude and longitude coordinates from the table, draw the path taken by the hurricane in red pen. Then use the green pen to draw the future path that you expect the hurricane to take.

if the thermos has a vacuum innner, then heat through conv currents and conduction are reduced = vacuum flask

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.
