Answer:
The Precambrian Era comprises all of geologic time prior to 600 million years ago. The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period.
Explanation:
GPE = mgh
m = mass=500g = 0.5kg
h= height = 2m
g = gravitational field strength, 9.8 near surface of earth
therefore GPE = 0.5*9.8*2 ( 0.5*2=1 so they cancel out), GPE = 9.8J
