Nitrogen has an outer shell with 5 electrons it needs 3 to make 8 and be stable
-- With two resistors in parallel, the total effective resistance is
the reciprocal of (1/R₁ + 1/R₂).
1/R₁ + 1/R₂ = 1/15 + 1/40
= 8/120 + 3/120
= 11/120
So the total effective resistance is 120/11 = 10.9 ohms .
Current = (voltage) / (resistance)
= 12 / (120/11)
= (12 · 11) / 120
= 132/120 = 1.1 Amperes
Answer:
The answer to your question is m₂ = 38.5 kg
Explanation:
Data
distance = d = 2.1 x 10⁻¹ m
Force = 3.2 x 10⁻⁶ N
m₁ = 55 kg
m₂ = ?
G = 6.67 x 10 ⁻¹¹ Nm²/kg²
Process
1.- To solve this problem use Newton's law of Universal Gravitation.
F = G m₁m₂ / r²
-Solve for m₂
m₂ = Fr² / Gm₁
2.- Substitution
m₂ = (3.2 x 10⁻⁶)(2.1 x 10⁻¹)² / (6.67 x 10⁻¹¹)(55)
3.- Simplification
m₂ = 1.411 x 10⁻⁷ / 3.669 x 10⁻⁹
4.- Result
m₂ = 38.5 kg
Answer:
A phase change is occuring; the liquid water is changing to gaseous water, or steam. On a molecular level, the intermolecular forces between the water molecules are decreasing. The heat is providing enough energy for the water molecules to overcome these attractive forces.
Explanation:
Answer:
Physical change
Explanation:
its changing matter but is still water so its not chemicly changing
