01.Velocity V of a stretched string depends on Tension T and mass per unit length M of the string. Create an equation for Velocity VUsing dimensional analysis.
02. A balloon is moving upward with velocity 36km/h, when it is 40m height from ground a particle dropped from it. (g=10m/s and there is no air friction) find,
a.Maximum height reached by the particle from ground
b.Time taken to the particle to reached the ground,
c.Velocity of the particle just before reach the ground.
03.A particle dropped from vertically downward from the top of the building, find the displacement of the nth second, 1st, 2nd, 3rd and 4thseconds.
04. P + ½ ρ v2 = constant, where P- pressure, ρ- Density, v- velocity. Show that the equation is dimensionally correct.
(Its v x v not v2)
