Answer: A
si, di, are expressed as negative and f is expressed as positive values.
Explanation:
When the object is located at a location in front of the focal point of a convex len, the image will always be located somewhere on the same side of the lens as the object. The image is located behind the object. In this case, the image will be an upright image and the image is enlarged
In this question, the relationship between the focal length, image distance di and object distance is
I/f = 1/di + 1/do that is
I/f - 1/di - 1/do = 0
The image size si is also negative since the image is a virtual image.
Therefore, si, di, are expressed as negative, f is expressed as positive values.

Explanation:
Given data:
diameter of solenoid is 11.1 cm
B = 42.9 mT
dR = 6.65 mT/s
d(1) = 4.34 cm
d(2) = 7.46 cm
we know that
electric field due to solenoid is given as
E = 1/2 dB/dt (r)
E = 1/2 dB/dt (R^2)/r
Answer:
Part a)
Part b)
Explanation:
As we know that capacitor plate is connected across 2.1 V and after charging it is disconnected from the battery
So here we can say that charge on the plates will remain conserved
So we will have
now dielectric is removed between the plates of capacitor
so new potential difference between the plates
Part b)
Now the capacitor plates are again isolated and unknown dielectric is inserted between the plates
So again charge is same so potential difference is given as
If a group of scientists have access to one data, from the data they can draw conclusions either through mathematics or just thought experiments.
Those thought experiments is different for any scientist, no one thinks the same especially when the topic is difficult.
For example when talking about parallel universes, scientists have come up with the weirdest examples of a multiverse. Some thinking of a brane universe, while others say that its a landscape universe, quilted universe. All of their 'evidence' seems correct but they have opposite meanings.
A weird analogy is 'religion'. All the religions seem to have 'evidences' (hardly) that attract people towards it, they all make sense but that doesn't mean that their evidence is right.

Now if they're trying to break down the data using maths, there could be a great uncertainty and measurement error that if done enough could change the whole idea behind the data.
Interesting question, I can babble for days for this but lets keep it as that
An atom is the smallest unit of matter. It can't be broken. It consist of dense nuleus surrounded by negatively charged electrons.
