Select all that apply. which of the following pure elements exist as liquids at normal earth temperatures? bromine nitrogen mercury gold oxygen

Bromine and mercury exists as liquids at normal Earth temperatures.

Explanation:

Pure elements which exists as liquids at normal Earth temperatures are bromine and mercury.

Whereas gold exist in solid phase. On the other hand, both nitrogen and oxygen exists as diatomic molecules and both of them are gases at normal Earth temperatures.

Thus, we can conclude that out of the given options only bromine and mercury are liquids at normal Earth temperatures.

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
