Question

На карандаш намотана проволока определить диаметр проволоки ,если на 4 см карандаша намотано 20 витков

Answer 1

Длину делим на количество витков
D=L/N
D=4/20=0,2см
Ответ 0,2 см

Answer 2

Calculating the Diameter of the Wire Wrapped Around a Pencil

To determine the diameter of the wire wrapped around the pencil, we can use the formula:

d = L / n

Where: - d = diameter of the wire - L = length of the wire - n = number of turns

Given that the wire is wrapped around 4 cm of the pencil and there are 20 turns, we can calculate the diameter of the wire using the formula.

Calculation

Using the given values: - L = 4 cm - n = 20

We can calculate the diameter of the wire: d = L / n d = 4 / 20 d = 0.2 cm

So, the diameter of the wire is 0.2 cm.
