The Breguet range equation [Eq. (1.45b)] applies for a cruise climb flight profile with constant RF. Another range equation can be developed for a level cruise flight profile with varying RF. Consider the case where we keep CL, Co, and TSFC constant and vary the flight velocity with aircraft

hotter stars = bluer stars

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )
