Answer:
The answer is 7.8 kJ / mol.
Explanation:
Energy = (number of methyl group) (Gauche interactions)(3.8kJ/mol per interaction)
= (2)(2)(3.8 kJ / mol)
= 15.2 kJ / mol.
The energy = (number of methyl group) - ( energy of gauche interactions)
= (23 kJ/mol) - 15.2 kJ/mol
= 7.8 kJ / mol.

I think the answer would be c
3. Kinetic energy
4. Potential energy
5. Kinetic energy because it’s moving towards the waterfall otherwise there wouldn’t be a waterfall.
6. Kinetic energy
7. Kinetic energy
8. Potential energy
9. Potential energy
10. Kinetic energy
The gravitational force between two objects is given by:

where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects
The distance of the telescope from the Earth's center is

, the gravitational force is

and the mass of the Earth is

, therefore we can rearrange the previous equation to find m2, the mass of the telescope:
