Ball a is attached to one end of a rigid massless rod, while an identical ball b is attached to the center of the rod, as shown in the figure. each ball has a mass of m =
0.450 kg, and the length of each half of the rod is l = 0.420 m. this arrangement is held by the empty end and is whirled around in a horizontal circle at a constant rate,
so that each ball is in uniform circular motion, ball a travels at a constant speed of va = 5.10 m/s. find (a) the tension of the part between a and b of the rod and (b)
the tension of the part between b and the empty end.

Asap time is ! best answer gets compose at least one well-developed paragraph on the following: define the term concurrent powers, and give an example of a concurrent power of government.

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
