work done = force * distance moved (in direction of the force)
force= mass* acceleration
force=58.1N
58.1*(5.8*10^4)
=3,369,800 J
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.
The ratio btw number of atoms.
example: water H2O is the compound. No matter how much water you take (a liter, 10 cubic meters... whole swimming pool), the proportion btw hydrogen atoms and oxygen would be always 2 to 1.
Answer
<span>D. The factor that's changed by the experimenter and impacts the dependent variable
</span>
Explanation
The term independent mean not interfered with. It stands on its on without been affected.
In an experiment the term independent factor is one which is not affected by another variable although it does change in the experiment but is is impacted by the dependent variable.
Answer:
b- absolute zero
*( And it's called zero kelvin)
