Question

Assume you've a rocket in earth orbit and want to go to Mars. The required change in velocity is ∆V=9.6km/s. There are two options for the propulsion system chemical and electric, each with a different specific impulse. Using ideal rocket eqn and setting go=9.81m/s^2
(1) Find cryogenic propulsion system w Isp 450 secs. Enter the required propellant fraction.
(2) Consider electric propulsion system w Isp 2000secs. Enter the required propellant fraction.​

Answer 1

Answer:

According to the Heisenberg's uncertainty principle, it is impossible to determine simultaneously, the exact position and exact momentum (or velocity) of an electron.
