Answer on Mechanics | Relativity Question for Irshad
What is artificial gravity how it is produced.If a space craft of length 20m enters in space then what should be its velocity to produce artificial gravity as earth.
Artificial gravity is an acceleration resulting from the application of a force. In the context of manned spaceflight, artificial gravity may alleviate the adverse health effects of prolonged weightlessness. Astronauts routinely experience intermittent linear accelerations caused by the force of a rocket engine. However, the term artificial gravity usually refers to a sustained Normal force provided by a rigid structure in uniform circular motion. Practical outer space applications of artificial gravity for humans have not yet been built and flown, principally because of the large size of the spacecraft required to produce a useful centripetal acceleration, comparable to little g.
Velocity has no meaning here. It must be g acceleration of 9.8 m/s2. The velocity will always growing.
Im very glad to use your service,last semester i used to stress over assignments even tho i knew how to do them but it used to put me in extra stress and specially having 5 courses with it made things hard,ever since i started using your service,it has removed alot of stress for me,im gettinf better grades now,100% in all my assignments till now,ive a humble resquest,i will keep following your website for many years,for your regular or frequent customers you should include some sort of discount other than that everything is perfect
