wave length is what he decreased
I would say c sorry if it’s wrong
<span>Hydration can occur when one mole of sodium acetate trihydrate is heated. Sodium acetate or NaC2H3O2 3H2O contains three water molecules within each unit in the crystal. The corresponding amount of hydration energy is already released when sodium acetate absorbs water and is then converted to sodium acetate trihydrate.</span>
Answer:
D. mass has a greater effect than height on gravitational potential energy
Explanation:
The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of gravitational potential energy the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.More massive objects have greater gravitational potential energy.
