An 8.0-kg history textbook is placed on a 1.25-m high desk. How large is the gravitational potential energy of the textbook-Earth system relative to the
floor?
i’ll give brainliest

GPE=98J if the given gravity is 9.8 but the gravity is 10 it will be 100J

Explanation:

GPE=mgh so m=8kg g=9.8m/s^2 or 10J h=1.25m

so GPE=8kg×9.8 or 10 m/s^2×1.25m

GPE=98J if the given gravity is 9.8 and GPE=100 if the given gravity is 10.but ask your teacher (asker) and don't forget those formula

a

explanation:

because they are cartillidge

ill do it for 100, also this isnt 80 its 40
