2 types
After extensive reaserch i belive the two propulsions in HEV's are your mum and go home :)
Concave mirrors and convex mirrors are two types of curved mirrors. Concave mirrors converge light rays to a focal point and can form real or virtual images. Convex mirrors diverge light rays and produce virtual, upright, and diminished images.
two types of star clusters are Open clusters and globular clusters
The two main types of terrain are Maria and Terrae.
The spacecraft used for the Apollo missions was called the Command/Service Module (CSM). It consisted of two parts, with the Command Module housing the crew during launch, re-entry, and splashdown, and the Service Module providing propulsion and life support systems.

Two types of propulsion in hybrid electric vehicles (HEVs) are series hybrid and parallel hybrid. In a series hybrid, the internal combustion engine only generates electricity to charge the battery which then powers the electric motor. In a parallel hybrid, both the internal combustion engine and the electric motor can work together to drive the vehicle.
Fuel & Gas
The two main types of propulsion are mechanical propulsion, which involves physical movement of an object through a medium such as air or water using engines or motors, and electromagnetic propulsion, which involves the use of electromagnetic fields to propel objects through space without the need for physical contact with a medium.
Umm...the question is a little vague (is it for a project, are there more details?), so I'll offer as much as I find relevant. You can split it into arm propulsion or leg propulsion. You can split it into the four strokes: butterfly, backstroke, breaststroke, freestyle. You can split it into surface propulsion and underwater propulsion. Be more specific and I can help you more.
well, first of all you shouldn't be using this site for an answer, and second of all, the two pruplosions are your mother and cow methane
LIQUID PROPELLENTS OR SOLID PROPELLANTS
name of two structure of soil
A hybrid is any car that uses two or more sources of power to drive or provide propulsion.
name the types of internal migration
The two main types of energy are kinetic energy, which is the energy of moving objects, and potential energy, which is stored energy that could be released at a later time.
