a) Southward you need to apply right hand rule. If you close your hand to the east, your thumb will indicate south.
b) Given the equation for Magnetic Force

Replacing


c) Given the second Newton's Law by


Given the electric force by,



Do you mean what order the Earth is in? The planets in order from closest to farthest from the sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto is technically just a dwarf planet but I'll include it anyways.
The correct answer is 0.67 h
The coil's induced emf is specified as e=0. 50 v.
i i = 0.55 A is the initial value of the current flow.
I f = 0.95 A is the total amount of current flowing.
The shift in current occurs in a period of time when dt = 0.40 s.
The self-inductance is determined as follows:
The current change rate is represented here by dI/dt.
Step 2 After entering the values,
As a result, the self-inductance is 0.67 H.
The definition of self inductance is the induction of a voltage in a wire that carries current when the current in the wire is changing. When there is self-inductance, a circuit's own changing current creates a magnetic field that causes a voltage to be induced.

A solar panel are most efficient under natural sunlight, however, a solar panel can work using artificial light simply because a solar panel collects photons which collide with silicon atoms transferring their energy which cause them to lose electrons.
