Work=mgh
(mass)(gravity)(height)
so (3.88)(9.81)(2.45)
=93.25 J (Joules)
245m
245 million written in scientific notation is 2.45 x 10^8. In scientific notation, a number is expressed as a coefficient multiplied by 10 raised to a certain power. In this case, 245 million is written as 2.45 (the coefficient) multiplied by 10 raised to the 8th power, as there are 8 zeros in a million.
