Before astronomers determined that PSR B1620-26 b was a planet, they went back and forth over its identity and thought that it could possibly be an object between the size of a planet and a small star. What did astronomers initially think that PSR B1620-26 b was? - brown dwarf
- global cluster
- moon
- star burst

Molybdeum(mo)orruthenium (ru)actually, elements with similar chemical properties as technetium would bemn, re, and bh. this is because elements in the same group/family (column) have similar chemical properties. elements in the same period (row) have the same number of energy levels (or shells).

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
