Answer:
is proved.
Explanation:
The magnetic field in the long current carrying wire is,

Here, I is the current, B is the magnetic field.
Now, by using cylindrical coordinates for the divergence of B.

Put the value of B in above equation.

Hence, it is prove that for a long current I carrying wire magnetic field divergence that is
.
The "D) People perceive objects as a whole" statement best describes an abductive reasoning. The abductive reasoning often has incomplete information as the base of its reasoning and the conclusion for this type of reasoning is not absolute. There will always be additional pieces of evidence and factors that could change the conclusion of this reasoning. Therefore<span> D statement is the most suitable answer.</span>
Answer:
Explained below:
Explanation:
The major limitation in the use of Photovoltaic cells to generate electricity is its unpredictability about the climate that whether it will be a shining day or a cloudy day and it does not work at night also because of no presence of sunlight as it totally depends on it. It can be used as an alternative but cannot be used as chief source of electricity.
Explanation:
I want to say option B - Both forces can act without objects touching.
Explanation:
Wavelength in an emission spectrum,
The energy of an electron is given by :

Where
h is the Planck's constant
c is the speed of light
For 435 nm, the energy of the electron will be :


We know that 
So, 
So, E = 2.86 eV
The energy of the electron dropping from one energy level is 2.86 eV. We know that,

From the given energy levels :

So, the transition must be from E₅ to E₂. Hence, this is the required solution.
