Answer:
Explanation:
If one assume that each turn is like a strand of electromagnet, which can then be added up. Therefore, increase in the number of turns will yield to increase in the magnetic strength. Also if the current increases, then there will be increase in the magnetic field strength.
From Ohm's law
V = IR
I = V/R
That is a direct increase in voltage will lead to increase in current.
Increase the voltage of the battery and increases the number of turns of the coil. Will suit the situation
Answer:
weight!!!! Free fall is the motion of a body where its weight is the only force acting on an object.
Answer - An object is in motion when its distance from another object is changing. ... A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point. You assume that the reference point is stationary, or not moving.
Answer:
AM broadcasts occur on North American airwaves in the medium wave frequency range of 525 to 1705 kHz (known as the “standard broadcast band”). The band was expanded in the 1990s by adding nine channels from 1605 to 1705 kHz.
Answer:
Explanation:
Gauss's Law says that the electric flux 
through a closed surface is directly proportional to the charge 
inside it. More precisely,
This means what is outside this closed surface 
does not contribute to the flux through it because field lines that go in must come out, <em>resulting a zero flux from an external charge. </em>
In our context, this means the charge 
which is outside the sphere will have zero flux through the surface; therefore, Gauss's law will only be concerned with charge 
which is inside the sphere; Hence,
Solving for gives
which is the charge inside the sphere.
