On a .75-meter table sits a book whose mass is .5 kilograms. How much Potential energy does it have?

P.E = 3.675  J

Explanation:

Given data:

Height of table = 0.75 m

Mass of book = 0.5 kg

Potential energy = ?

Solution:

Formula:

P.E = mgh

g =acceleration due to gravity =  9.8 m/s²

by putting values,

P.E = 0.5 kg× 9.8 m/s² ×0.75 m

P.E  = 3.675 kgm²/s²

J = kgm²/s²

P.E = 3.675  J

Explanation:

Gravitational potential energy can be found using the following formula.

Where m is the mass, g is the gravitational acceleration, and h is the height.

The mass of the book is 0.5 kilograms. The acceleration due to gravity on Earth is 9.8 m/s². The height of the book is 0.75 meters.

Substitute the values into the formula.

Multiply.

The book has 3.675 Joules of gravitational potential energy.

the answer is b & c i believe : )

that's what i got you can count the number of atoms
