If you could only see the lights in the circuit and the wires were covered from view, how could you determine the type of circuit the lights are arranged in? a) if all the lights are equal brightness, it is a series circuit. b) if you add another bulb and it gets dimmer, it is a parallel circuit. eliminate c) unscrew one light, if the others remain on it is a series circuit. d) unscrew one light, if the others remain on it is a parallel circuit.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

Velocity=total displacement/timefrom house to store is 500 from store to neighbor is 200 therefore total displacement=500+200=700metrestherefore,700metres/910seconds=0.8metres per second
