I know for a fact the answer would (not) be the last option. This would not be a way that electricity would be able to really flow.
Your correct answer would be of when the
"e<span>
lectrons flow from the negative end of a source towards the positive end."This would be because when the electrons would be free, they would have enough energy to then move from the negative side of the end, to the positive side.</span>
Answer: 5m
Explanation:
Given that:
Wavelength (λ)= ?
Frequency of wave (F) = 60MHz
[If 1 MHz = 1,000,000 Hz
60MHz = 60 x 1,000,000 = 6 x 10^7Hz]
Speed of wave (V) = 3 x 10^8 m/s
The wavelength is the distance covered by the wave in one complete cycle. It is measured in metres, and represented by the symbol λ.
So, apply the formula V = F λ
Make λ the subject formula
λ = V/ F
λ = 3 x 10^8 m/s / 6 x 10^7Hz
λ = 5m
Thus, the wavelength of an electromagnetic wave is 5 metres.

Answer:
8.1%
Explanation:
<h3><u><em>mass of glucose/ total mass of solution x 100</em></u></h3>
So first 265mg into grams = 0.265 g
0.265 + 3 = 3.265
mass of glucose= 0.265
total mass of solution= 3.265
0.265/3.265 x 100 = 8.1% (rounded to 2 s.f)
Answer:
K = 0.5
Explanation:
Based on the reaction:
PCl₃ + Cl₂ ⇄ PCl₅
The equilibrium constant, K, is defined as:
K = P PCl₅ / P PCl₃ * P Cl₂
<em>Where P represent the pressure at the equilibrium for each one of the gases involved in the equilibrium.</em>
<em />
As:
P PCl₅ = 1.0atm
P PCl₃ = 1.0atm
P Cl₂ = 2.0atm
K = 1.0atm / 1.0atm * 2.0atm
<h3>K = 0.5</h3>
