The Earth .

has a circular orbit around the sun

is tilted 23 1/2° on its axis

rotates from west to east

bulges slightly at the equator

revolves around the sun once every 365 1/4 days

The Earth:

Explanation:

The only option that is incorrect is the first one - The Earth has a circular orbit around the sun-. Although the Earth has an orbit around the sun, this one is not circular, it is elliptical, this is similar to an inclined oval, and the planet rotates in this orbit with an inclination on its axis of 23 1/2º.

As well as the shape of the orbit is not circular, the shape of the Earth is not equal in all its parts, it is wider in the equator in comparison with the North and South Poles.

It rotates from west to east in its axis, and it takes 365 1/4 days to complete a round in its orbital.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
