within the last 30 yearscaused<span> by burning fossil fuels has been identified as
the major </span>reason<span> for
the change of temperature in the atmosphere (click the following link for a

The book is lifted upward, but gravity points down, so the work done by gravity must be negative (so you can eliminate options 1 and 3).
The force exerted on the book by gravity has magnitude
<em>F</em> = <em>mg</em> = (10 N) (9.80 m/s^2) = 9.8 N ≈ 10 N
You raise the book 1.0 m in the opposite direction, so the work done is
<em>W</em> = (10 N) (-1.0 m) = -10 J
Answer:
im pretty sure it is 3.0 K
