As you lift a book into the air, what kind of energy are you increasing in the book? a. nuclear energy b. thermal energy c. gravitational potential energy d. elastic energy

As you lift a book into the air Gravitational potential energy will increase  in the book.

Option C

Explanation:

Gravitational potential is referred as the energy spent to move the mass from one point to another. The formula is  m * g * h. When a book is lifted, there is a change in position, therefore the gravitational potential energy used is increased because the gravitational force is acting upon the object (i.e) the book. Option A,B, and D are invalid in this situation.

wavelength divides in half and speed stays the same.
