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?
Expert
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.
Describe briefly all the Law of Machines?
Wiedemann-Franz law: It is the ratio of the thermal conductivity of any pure metal (substance) to its electrical conductivity is just about constant for any specified temperature. This law holds pretty well apart from at low temperatures.
I have a problem in wirting a report on Radiobiology for Travel Space. Can someone provide me a complete report on the above topic.
Briefly explain the procedure to define the Specific Gravity?
Negative feedback principle: It is the idea that in a system where there are self-propagating situations, those new situations tend to act against formerly existing situations. Such a principle is in actuality a restatement of the conservation law.
Thomson experiment: Kelvin effect (Sir W. Thomson [later Lord Kelvin]): Whenever an electric current flows via a conductor whose ends are maintained at various temperatures, heat is discharged at a rate just about proportional to the

Explain Thermodynamic laws and also First law, Second law, third law and zeroth law of thermodynamics? Thermodynamic laws: Q : Explain Ohms law Ohm's law (G. Ohm; Ohm's law (G. Ohm; 1827): The ratio of the potential difference among the ends of a conductor to the current flowing via it is constant; the constant of proportionality is termed as the resistance, and is distinct for different materials.
