The semimajor axis of a hyperbolic orbit is always larger than the semimajor axis of an elliptical orbit.

For velocities larger than the escape velocity, the orbit is always a parabola.

The eccentricity of an elliptical orbit is negative, and the eccentricity of a hyperbolic orbit is positive.

The energy of an elliptical orbit is negative, and the energy of a hyperbolic orbit is positive.

None of the answers is correct.

the squared of the period is proportional to the cubed of the semimajor axis.

the cubed of the period is proportional to the squared of the semimajor axis.

None of the answers is correct.

the period is proportional to the cubed of the semimajor axis.

Chemical propulsion provides higher thrust-to-weight ratios.

All answers are true.

Cold-gas thrusters provide the smallest specific impulse.

Electrostatic propulsion provides higher specific impulse than chemical propulsion.

the rotation of Earth already provides about 0.5 km/s delta-v towards the East.

the good weather conditions increase the success rate.

there is more ocean than land and hence there is less risk in case of launch failure.

None of the answers is correct.

are more complex and hence less used.

All answers are incorrect.

have higher specific impulse.

are throttled more easily.
