Answer:
Use a more magnetic material
Use more fields
Explanation:
The magnetic energy is a special energy in substances. This is the energy possessed by ferric metals. In other terms, these are metals that have a lot of delocalized electrons. The transition metals are magnetic. The most magnetic metal is iron. The magnetic power of iron is in the domains in the metal. The domains are the movements of the particles in the magnetic field. These correspond to the earths magnetic field. The potential energy can be increased by incorporating electricity. The electricity makes the domains to take a certain direction in the field.

Explanation:
Hello!
In this case, since this is a two-step conversion, we first need to compute the m² and then the km² as shown below:
Now from m² to km²:
Best regards!
Answer:
Explanation:
time to diffuse x cm is given by the relation
t = X² /2D
D = 5.7 x 10⁻⁷
t = X² / 2 x 5.7 x 10⁻⁷ = X² x 10⁷ / 11.4 s
X = 10 pm = 10 x 10⁻¹² m = 10 x 10⁻¹⁰ cm = 10⁻⁹ cm
t =( 10 ⁻⁹)² x 10⁷ / 11.4 = 10⁻¹¹ / 11.4 = 8.77 x 10⁻¹³ s
Answer:
The answer to your question is 22.5 moles of H₂SO₄
Explanation:
Data
moles of H₂SO₄ = ?
moles of Al = 15
Balanced chemical reaction
2Al + 3H₂SO₄ ⇒ Al₂(SO₄)₃ + 3H₂
To solve this problem use proportions and cross multiplication. Use the coefficients of the balanced chemical reaction.
2 moles of Al ------------------- 3 moles of H₂SO₄
15 moles of Al ------------------ x
x = (15 x 3) / 2
x = 45/2
x = 22.5 moles of H₂SO₄
-Conclusion
22.5 moles of H₂SO₄ react completely with 15 moles of Al.
Answer:
theory
If it has been tested enough, then it can be considered a scientific theory.
