Điện trở của đây dẫn phụ thuộc vào chiều dài là tiết điện như thế nào?

The objects do not reach terminal velocity         there is not enough time from the time the object falls from when it hits the ground to achieve terminal velocity. an object must be placed higher to achieve terminal velocity in order to be in free fall.

You can find results and justify them? you can test your hypothesis

Iwould think it is temperature, silica, oxides (gases)

Answervery cold;
