The answer is C. Since you have to have electrons spinning the same direction to form a magnetic field.
Answer:
The resistance added to this coil is 0.04 ohm in parallel.
Explanation:
Given that,
Current I'= 0.5 A
Resistance R= 20 ohm
Deflection I= 1 mA
We need to calculate the resistance
Using ohm's law
Where,
V = voltage
I =current
R = resistance
V is constant so ,
Therefore,
I R=I'R'
Hence, The resistance added to this coil is 0.04 ohm in parallel.
When in a car, you are moving, the car is moving but when you stop the car or crash the car you keep moving even after the car stops, the air bag puts a opposite force on you so you dont fly out the window please mark as brailiest? :)
Answer:
Two correct answers (the first one and the last one listed):
<em>Atoms with the same atomic number have the same number of electrons. </em>
<em>Atoms with the same atomic number can have different numbers of neutrons.</em><em> </em>
Explanation:
There are two correct answers:
<em>Atoms with the same atomic number have the same number of electrons. </em>This is because neutral atoms have the same number of electrons than of protons in the nuclei. And the number of protons in the nucleus characterize the particular element and is called the "Atomic number."
and
<em>Atoms with the same atomic number can have different numbers of neutrons.</em><em> </em>These constitute the isotopes of the element characterized by the given atomic number.
