Yes!
Yes, the London dispersion force is very weak.
Dipole-Dipole and covalent sigma bond forces.
The only intermolecular forces in this long hydrocarbon will be dispersion forces.

Dipole-dipole and dispersion
The London dispersion force is considered as the weakest intermolecular force. The production of an instantaneous dipole in London dispersion is only temporary.

yes, CH4 has London dispersion forces because it is a non-polar molecule and non-polar molecules have London dispersion forces present in them. there are no other forces present in CH4.
