BY PYTHAGORAS THEOREM H2=P2+R2. ,,, P2=H2-B2. NAD ANSWER IS (B) √27
the state or quality of being efficient.
"greater energy efficiency"
Answer
Efficiency is the ability to avoid wasting materials, energy, efforts, money, and time in doing something or in producing a desired result.
Answer: The magnitude of force per length that each wire exert on the other wire is 2.67×10^-5 N/m.
The force is repulsive.

<h3><u>
Answer:</u></h3>
5 * 10² m
<h3><u>
Explanation:</u></h3>
<u>We are Given:</u>
Frequency of the wave = 6 * 10⁵ Hz
<u>Wavelength of the wave:</u>
We know the relation:
c = λν <em> </em>
<em>[where λ (Lambda) is the wavelength ,ν (nu) is the frequency and c is the speed of light ]</em>
3 * 10⁸ m/s= (6 * 10⁵ )* λ <em> </em>[<em>replacing known values</em>]
λ = [dividing both sides by 6 * 10⁵]
λ = 1/2 * 10³
λ = 1/2 * 10 * 10² [10³ can be rewritten as 10 * 10²]
λ = 5 * 10² m
Therefore, the wavelength of the wave is 5 * 10² m
