Answer:
Explanation:
magnetic flux is the count of magnetic field lines passing through a given loop or area
As we know that magnetic flux is given by the formula
here we also know that magnetic field B and plane of the coil is perpendicular in initial position
So the area vector is always perpendicular to the plane of the coil
so the angle between magnetic field and area vector is parallel to each other and this angle would be zero
so magnetic flux of the coil initially we have
When you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.
Given :
A copper plate of mass 3.0g.
Atomic number, z = 29.
Atomic mass, M.M = 63.5 g/mol.
Avogadro's number, .
Charge on electron, .
To Find :
The total charge of all the electrons.
Solution :
Moles of copper,
Number of atoms in 0.047 moles of copper :
Since, there are 29 electrons on each atoms.
So, total charge is :
Hence, this is the required solution.
