WebIn simple words, angular velocity is the time rate at which an object rotates or revolves about an axis. Angular velocity is represented by the Greek letter omega (ω, sometimes Ω). It is measured in angle per unit time; hence, the SI unit of angular velocity is radians per second. The dimensional formula of angular velocity is [M 0 L 0 T -1 ]. WebAt the terminal velocity, Fnet = mg − FD = ma = 0. Thus, mg = FD. Using the equation for drag force, we have mg = 1 2CρAv2T. Solving for the velocity, we obtain vT = √2mg ρCA. Assume the density of air is ρ = 1.21kg/m3.

WebSample Questions. Ques. A copper wire has a cross-sectional area of 7.85 x 10-7 m2. The number density of copper is 8.5 x 1028 m-3. Calculate the mean drift velocity of the electrons through the wire when the current is 1.4 A. (3 marks) Ques. A wire of diameter 0.02 meter contains 1028 free electrons per cubic meter. WebThese facts can be used to derive the range of the projectile, or the distance traveled horizontally. At maximum height, v y = 0 and t = T/2; therefore, the velocity equation in the vertical direction becomes 0 = v o sin θ − g T/2 or solving for T, T = (2 v 0 sin θ)/ g. Substitution into the horizontal distance equation yields R = ( v o cos ... the painting he bought at the street
