What quantity does the gradient of the distance-time² graph represent? Briefly justify your answer

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.

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.

you get 2.3=1.21*\frac{a}2 or 4.6=1.21a or a=3.802 (b)
