Answer:
The answer to the question is 2.2khz
Explanation:
<em>Let z₁ = 5.4m</em>
<em>Let z₂ = 4.6m</em>
<em>The path difference Δz = z₁-z₂ = 5.4 - 4.6 = 0.8m</em>
<em>For the interference= Δz λ, 2λ, 3λ......</em>
<em>The wavelength λ = 0.8m</em>
<em>The speed of sound v = 344m/s</em>
<em>The frequency f = v/λ = 344/0.8 = 430hz</em>
<em>Now,</em>
<em>f₁ =f, f₂= 2f, f₃ = 3f, f₄= 4f, f₅ =5f which is,</em>
<em>f₁ =f = 430Hz, f₂=2f =860Hz, f₃ =3f =1290Hz f₄ =4f =1720Hz and f₅=5f =2150Hz</em>
<em>f5 = 2120Hz = 2.200Hz </em>
<em>we will convert to two significant figures =2.2kHz</em>

Answer:
The magnetic flux through the desk surface is 
.
Explanation:
Given that,
Magnetic field B = 0.42 T
Angle =68°
We need to calculate the magnetic flux
Where, B = magnetic field
A = area
Put the value into the formula
Hence, The magnetic flux through the desk surface is .

National Industrial Goods and Technology Expo- Glocal Khabar
Kathmandu, February 19, 2018: Cottage and Small Industries Development Committee is set to organize the twenty-ninth edition of National Industrial Goods and Technology Expo from March 23, 2018 at Bhrikutimandap, Kathmandu.
The motto of the five-day event is ‘Let’s use home-made products, move ahead towards prosperity.’ The committee has shared that handicrafts, wool and bamboo products, goods made from handmade papers, different types of pickles and Palpali Dhaka would be put on display in the expo.
By dropping a ball and seeing how long it takes to hit the ground or throw a ball up and time it as well
The voltage from one side of the battery all the way around to the other side of the battery is 12v .
If 4 of those volts show up across the circle-thing, then the rest of the 12v ... 8v ... Must show up across the set of parallel rectangles.
To get that answer, I subtracted the 4 from the 12.
Just like it says in choice-C.
