Answer:
It is very rare to see a solar eclipse from your home, because the Earth, Sun, and the moon need to align just right. Not everyone in the world can view a solar eclipse, only some area can. A solar eclipse is where the moon blocks out the sun. If you think about it: Let's say you live in Florida, U.S.A. You may see the moon coming in front of the sun, but if you lived in California or sumthin', the moon and the sun wouldn't be aligned to form a solar eclipse. It all depends on location... so it is rare to see one.

The sphere’s Electric potential energy is 1.6*
J
Given,
q=6. 5 µc, V=240 v,
We know that sphere’s Electric potential energy(E) = qV=6.5*
=1.6*J
<h3>Electric potential energy</h3>
The configuration of a certain set of point charges within a given system is connected with the potential energy (measured in joules) known as electric potential energy, which is a product of conservative Coulomb forces. Two crucial factors—its inherent electric charge and its position in relation to other electrically charged objects—can determine whether an object has electric potential energy.
In systems with time-varying electric fields, the potential energy is referred to as "electric potential energy," but in systems with time-invariant electric fields, the potential energy is referred to as "electrostatic potential energy."
A tiny sphere carrying a charge of 6. 5 µc sits in an electric field, at a point where the electric potential is 240 v. what is the sphere’s potential energy?

The electromagnet is a device that requires conducting wires wrapped around the iron core.
For making an electromagnet, the most necessary item is a copper wire.
What is an Electromagnet?
An electromagnet is a device that has conducting wires wrapped around an iron core. When electricity is passed through the wires, a magnetic field is generated. The setup acts as a strong magnet.
In order to make an electromagnet, a current-carrying wire is needed to wrap around a magnetic material. The current-carrying wires will play the role of conducting wires and the conducting wires are necessary to make an electromagnet. These wires can be made of copper.
Thus, we can conclude that for making an electromagnet, the most necessary item is a copper wire.
