BaLLatris [955]
<span>to find the scale factor, the main formula which is used for solving such a problem is as follow: If the initial shape is greater than the final's, so we use SF=SL / LL. SF= scale factor, SL=Smaller length, LL= Larger legth. According to our case, the smaller length is SL=6mm, and the Larger length is LL=15mm, so SF=6mm/15mm=2/0.4mm.The answer is SF=0.4mm</span>

Evgesh-ka [11]

Answer:

  • D. The experimental data does not support Sally’s hypothesis.

Step-by-step explanation:

<u>Sally's hypothesis can be shown as:</u>

  • 8c = 1p, where c- coil, p- paper clip

<u>From the data in the table we can see that:</u>

  • 8c = 2p ⇒ 4c = 1p
  • 16c = 4p ⇒ 4c = 1p
  • 24c = 6p ⇒ 4c = 1p

As we see there is a difference, Sally can pick up one paper clip for each 4 coils.

Correct answer choice is D.
