Derive the equation ignition V=Vo+at from v-tgraph​

Answer»

-v = u + atTO DERIVE :-First equation of motion (v = u + at)DERIVATION :-Let us consider an OBJECT is moving with uniform acceleration along a straight line . Let (u) be the initial velocity at t = 0 . After interval of time (t) , its velocity becomes u.➳ Let OA = u [ t = 0 ]Here in the figure we draw AD ⟂ BC , and BE ⟂ OY.➳ ∠BAD = ϴ. [ say ]Now,➳ Acceleration = SLOPE of Line AB➳ a = TAN ϴ➳ a = BD/AD. [ tan ϴ = P/B ]➳ a = (v - u)/t. [ AD = OC = t ]or, at = v - u.or, v = u + at. [ 1ST Equation of motion ]Hence we proved the required equation of motion (v = u + at)

If the speed of a wave is 380m/s and it's frequency is 1900Hz, then the wavelength of the wave will be:​

Answer»

Wavelength of the wave = 0.2 metresExplanation:Given:Speed of wave, V = 380 m/sFrequency of wave, f = 1900 HzTo find:Wavelength of the wave, λ =?Formula required:RELATION between Wavelength, FREQUENCY and speed of a wave         λ = v / f [ Where λ is wavelength, v is speed of wave, f is frequency of wave ]Solution:Using formula → λ = v / f → λ = ( 380 ) / ( 1900 )→ λ = 38/190→ λ = 0.2  mTherefore,Wavelength of the given wave is 0.2 METRES.
