. 1. How do solar panels or calculators work when sun light hits them? Eynlain bocalar​

Explanation:

When the light from the sun hits a solar panel, the absorption of light raises an electron to a higher energy state. Then, the movement of this higher energy electron creates the electric field.

When sunlight hits a solar cell, also known as a photovoltaic cell - meaning“light” and voltaic meaning “electricity” ,which energy can be transformed into an electric current. This influx of energy knocks loose electrons from the silicon atoms, allowing them to move freely.

In guessing 7 cm is the width and 14 cm is the are so you divide
X*7cm=14 cm
7x=14
Divide by 7 to get x by itself
x=2
The length is 2cm
