Answer:
Since then only three elements on the periodic table have been found to be ferromagnetic at room temperature - iron (Fe), cobalt (Co), and nickel (Ni). The rare earth element gadolinium (Gd) nearly misses by only 8 degrees Celsius.
Explanation:
Answer:
b
Explanation:
air mass surrounding the earth
Answer:
The first one with the big plus in the middle and negatively charged electrons around.
Explanation:
I think thats a trick question on the periodic table there is no Z, theres Zi which is zinc but no Z
A. The magnitude (in N) of the electric force that one particle exerts on the other is 8.60×10⁻⁸ N
B. The force is repulsive
<h3>A. How to determine the magnitude of the electric force</h3>
From the question given above, the following data were obtained:
- Charge 1 (q₁) = 7.03 nC = 7.03×10¯⁹ C
- Charge 2 (q₂) = 4.02 nC = 4.02×10¯⁹ C
- Electric constant (K) = 9×10⁹ Nm²/C²
- Distance apart (r) = 1.72 m
- Force (F) =?
The magnitude of the electric force can be obtained by using the Coulomb's law equation as shown below:
F = Kq₁q₂ / r²
F = (9×10⁹ × 7.03×10¯⁹ × 4.02×10¯⁹) / (1.72)²
F = 8.60×10⁻⁸ N
<h3>B. How to determine whether the force is attractive or repulsive</h3>
From the question given, we were told that:
- Charge 1 (q₁) = 7.03 nC
- Charge 2 (q₂) = 4.02 nC
Since both charge are positive, then the force attraction between them is repulsive as like charges repels and unlike charges attracts
