Light ray is travelling from the angle of incidence and angle of reflection respectively |
| Answer» TION:The LAW of reflection states that, on reflection from a smooth surface, the ANGLE of the reflected ray is equal to the angle of the incident ray. (By CONVENTION, all angles in geometrical optics are measured with RESPECT to the normal to the surface—that is, to a line perpendicular to the surface.) | |

If voltage across a conductor is (4+_0.1) and current is (2+ 0.1) Find resistance of conductor with error limit? |
|
Answer» 2+_ 0.15 Ω MARK as brainliestExplanation:Here, V= 4 V , I = 2 A and Δ V = 0.1 V and Δ I = 0.1 A Now, R= V/I = 4/2 = 2 Ω for ERROR, Δ R /R = Δ V/ V + Δ I /I or, Δ R = R * (Δ V/ V + Δ I /I ) = 2 * (0.1 / 4 + 0.1 / 2) = 0.15 Ω So, RESISTANCE is 2+_ 0.15 Ω |

Q. explain and solve differential equation of simple harmonic oscillator.... |
|
Answer» d2xdt2=−kmx. This is the differential EQUATION for simple harmonic motion with n2=km. HENCE, the period of the motion is given by 2πn=2π√mk. We can conclude that the larger the MASS, the longer the period, and the STRONGER the spring (that is, the larger the stiffness constant), the shorter the period. |

A transverse harmonic wave on a string is described by y(x,t)=2.0sin(36t+0.018x+π/4) where x and y are in cm and t in s. The positive direction of x is from left to right. (a) Is this a travelling wave or a stationary wave? If it is travelling what are the speed and direction of its propagation? (b) What are its amplitude and frequency? (c) What is the initial phase at the origin? (d) What is the least distance between two successive crests in the wave? |
|
Answer» Open_in_app(a) The equation of progressive wave travelling from right to left is GIVEN by the displacement function:y(x,t)=asin(ωt+kx+ϕ) ... (i)The given equation is:y(x,t)=3.0sin(36t+0.018x+ 4π ) ...(ii)On comparing both the equations, we find that equation (ii) represents a travelling wave, propgating from right to left. Now using equations (i) and (ii), we can write:ω=36 rad/s and k= 0.018 m −1 We know that:v=ω/2π and λ=2π/kAlso,v=fλ∴v=(ω/2π)×(2π/k)=ω/k =36/0.018=2000cm/s=20m/sHence, the SPEED of the given travelling wave is 20 m/s.(b) AMPLITUDE of the given wave, a=3cmFrequency of the given wave:f=ω/2π=36/2×3.14=573Hz(c) On comparing equations (i) and (ii), we find that the INTIAL phase angle, ϕ=π/4(d) The DISTANCE between two successive crests (or troughs) is equal to the wavelength of the wave.Wavelength is given by the relation: k=2π/λ∴λ=2π/k=2×3.14/0.018=348.89cm=3.49mhope it helps you.... |
