Estimate how long a galaxy in the coma cluster would take to travel from one side of the
cluster to the other. assume that the galaxy moves with a constant speed equal to the cluster’s
radial velocity dispersion. how does this compare with the hubble time, th ? what can you
conclude about whether the galaxies in the coma cluster are gravitationally bound?

Nacidified solution was electrolyzed using copper electrodes. a constant current of 1.18 a caused the anode to lose 0.584 g after 1.52 ✕ 103 s. given that the charge of an electron is 1.6022 ✕ 10−19 c, calculate avogadro's number. assume that copper is oxidized to cu2+ ions.
