A person who has a weight of 165 pound-force [lb f ] on Earth is travelling to Mars in a spacecraft. As long as the engines on the spacecraft are not operating, the person is essentially weightless during the voyage. During a course correction, the spacecraft undergoes an acceleration of 0.72 “g”. The term “g” is the Earth-normal gravity, so 1 “g” is 9.8 meters pe r second squared [m/s 2 ]. This acceleration makes it “feel” like there is gravity in the spacecraft, and the person will have a perceived weight during the acceleration period, rather than feeling weightless. Once the person reaches Mars, what is the mass, in units of kilograms [kg], and weight in units of pound-force [lb f ], of the person on Mars? The gravity of Mars is 3.71 meters per second squared [m/s 2 ].

A person who has a weight of 165 pound-force [lbf] on Earth is travelling to Mars in a spacecraft. As long as the engines on the spacecraft are not operating, the person is essentially weightless during the voyage. During a course correction, the spacecraft undergoes an acceleration of 0.72 “g”.

The following processes occurs in a reversible thermodynamic cycle:
1-2: Reversible polytropic compression at pressure [X] bar at volume [Y] m3 to a pressure [Z] bar and specific volume [A] m3/kg. The index of compression may be taken as n.
2-3: Reversibly expansion with expansion index of 2 to pressure [B] bar.
3-1: Reversible cooling at constant volume to the initial state.
What are the final attempt values of X, Y, Z, A and B from the Part A of the eThuto Assessment. calculated formula similar question?

An insulated, constant-volume system containing 1.36 kg of air receives 53 kJ of paddle work. The initial temperature is 27 C. Determine (a) the final temperature [1 decimal place] and (b) the change of internal energy [whole number].
The gravitational constant g is 9.807 m/s² at sea level, but it decreases as you go up in elevation. A useful equation for this decrease
In g is g= a - bz, where z is the elevation
above sea level, a = 9.807 m/s², and b=3.32 x 10-61/s². An astronaut "weighs" 80.0 kg at sea level. [Technically this means that
his/her mass is 80.0 kg.] Calculate this person's weight in N while floating around in the International Space Station (z=325 km). If the
Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel Immediately after the satellite
stopped moving?
