Problem on Orbit cycle
Calculate the hot and cold temperature after 25 orbits. Assume a 100kg spherical spacecraft made of aluminum. Assume that the spacecraft is in an equatorial orbit. How is calculation 1 different for a spacecraft in a 90 degree (polar) orbit?

The average temperature first lowers and then its increased. Each orbit cycle adds the temperature of 3.75 degree centigrade. 25 orbit simulation causes 25 degree .
The hot temperature goes to 65 degree centigrade.
Generally temperature varies from -71 to 51 degree.In case of polar orbits The average temperature is increased. Each orbit cycle adds the temperature of 4.25 degree centigrade. 25 orbit simulation causes 42 degree.
The hot temperature goes to 87 degree centigrade.
Explain laws of black-hole dynamics or First law of black hole dynamics and Second law of black hole dynamics? Q : Define Radian or SI unit of the angular Radian: rad: The supplementary SI unit of the angular measure stated as the central angle of a circle whose subtended arc is equivalent to the radius of the circle.
Radian: rad: The supplementary SI unit of the angular measure stated as the central angle of a circle whose subtended arc is equivalent to the radius of the circle.
Second: s: The basic SI unit of time, stated as the period of time equivalent to the duration of 9 192 631 770 periods of the radiation analogous to the transition between the two hyperfine levels of the ground state of cesium-133 atom.

Siemens: S (after E.W. von Siemens, 1816-1892): The derived SI unit of an electrical conductance equivalent to the conductance of an element which has a resistance of 1 O [ohm]; this has units of O-1.
Pascal: Pa The derived SI unit of pressure stated as 1 N acting over a region of 1 m2; it therefore has units of N/m2
Pseudoforce: The "force" that arises as an observer is plainly treating an accelerating frame as an inertial one.
Becquerel: Bq (after A.H. Becquerel, 1852-1908) - The derived SI unit of the activity stated as the activity of radionuclide decay at a rate, on the average, of one nuclear transition every 1 s; it hence has units of s-1.
