A metal pipe is 77 cm long. The inner diameter of a cross section is 4 cm, the outer diameter being 4.4 cm (see figure). Find its.

Wonderful solution. I love it. Thank you so much

Here, r = 3. 5/ 2 m , h = 10 m  (i) Inner curved surface area of the well  = 2πrh = 2 × 22/ 7 × 3. 5 /2  × 10m2  =...

Here, inner radius (r) = 24/ 2 cm = 12 cm  Outer radius (R) = 28/ 2 cm = 14 cm, h = 35 cm  Volume of the wood used in the...

Inner transition metals are those elements in which the last electron enters the f-orbital. The elements in which the 4f and the 5f orbitals are progressively filled are called f-block...

(b) : Centripetal force on particle = mRω2  Therefore, F1/F2 = (mR1ω2)/(mR2ω2)= R1/R2.

Length of wire  L= 3 m,  Load F = 10*10 N =100 N, {taking g = 10 m/s²}  Area of cross-section A = 4 mm²  →A = 4x10⁻⁶ m²  (a) The stress = Load...

(b) minimum at the axis of the wire (c) maximum at the surface of the wire

Since the Pipe is double the size, it will take1/2 time of the time taken by the smaller pipe Therefore 1/2x4 =2 hrs

For open organ pipe, fundamental frequency we take n=1 For closed organ pipe, third harmonic we take n=2 so answer is correct

There are nine gates on the outer walls of the fort.
