Edrops Epuddle If a puddle of liquid on a table is converted into a collection of 28 drops, by what factor c = does the surface energy change? Round your answer to two decimals. Assume that the original pool was flat with a depth of 1.2 mm and that the drops are spherical caps (you can Google this), each with a height of 4.0 mm and a radius of 10.5 mm. The side area of the puddle can be neglected. c =

• Problem 3.22 The potential energy between the atoms of an hydrogen molecule can be modelled by means of the Morse potential -2(r – ra) (r V (r) = V exp 2 еxp where Vo = 7 × 10 12 erg, ) = 8 x 10-º cm and a = 5 x 10-º em.
Find the answer for the given: Let L be the length. Let M be the mass. A rod that has L and M was hunged from the one end of a frictionless pivot, and it was hanged vertically at rest (intially) A person fired one small ball of clay with mass (m) to the rod with a speed V(initial) and stuck to the end of the non pivoted area. Find the angle Of greatest rotation for the rod/clay system? M M,L V(initial)
a.) A particle with mass m is dropped with zero initial velocity a height h above the ground, under the action of the gravitational field (acceration constant g), such that it reaches the ground (z=0) with zero potential energy and velocity v>0. Determine h, in terms of the other quantities given. b.) Another particle moves with Simple Harmonic Motion with centre O.The particle has velocity 13ms–1 when it is 3m from O and 5ms–1 when it is 5m from O.(i) Find the period and amplitude of the motion
(a) What does the quadrupole formula (P) = = = (Qij Q³ ³) compute? Reason the answer. (b) A point mass m undergoes a harmonic motion along the z-axis with frequency w and amplitude L, x(t) = y(t) = 0, z(t) = L cos(wt). Show that the only non-vanishing component of the quadrupole moment tensor is = Im L² cos² (wt). (c) Use the quadrupole formula to compute the power radiated by the emission of gravitational waves. (Hint: recall that (cos(t)) = (sin(t)) = 0 and (cos² (t)) = (sin² (t)) = ½½ for a given frequency 2.)
