According to the question, the object is placed at 2F
The ray diagram is shown in the figure attached.
According to the figure:
Object AB is at 2F₁
First, we draw a ray parallel to principal axis.
So, it passes through focus after refraction.
We draw another ray which passes through optical center.
So, the ray will go through without any deviation.
Where both refracted rays meet is point A' and the image formed is A'B'
This image is formed at 2F₂
We can say that:
- Image is real.
- Image is inverted.
- Image is exactly the same size as the object.
Electrical current will flow through a solid by the means of
electrons. The electrons in the solid
must be able to move from lower to higher electrical potential. The electric
current in certain solid electrolytes like ice is entirely composed of flowing
ions.
The amount that Mary will pay in social security taxes will be $1550.
<h3>How to compute the value?</h3>
It should be noted that the current tax for the social security is 6.2% for the employer and 6.2% for the employee.
In this case, let's assume that the income for Mary is $25000, the amount that Mary will pay will be:
= 6.2% × $25000
= 0.062 × $25000
= $1550
