Explanation:
Sensor/Detectors/Transducers are electrical, opto-electrical, or electronic devices composed of specialty electronics or otherwise sensitive materials, for determining if there is a presence of a particular entity or function. Many vehicles including cars, trains, buses etc. all use sensors to monitor oil temperature and pressure, throttle and steering systems and so many more aspects.
Answer:
eccentrcity of orbit is 0.22
Explanation:
GIVEN DATA:
Initial velocity of satellite = 8333.3 m/s
distance from the sun is 600 km
radius of earth is 6378 km
as satellite is acting parallel to the earth therefore![\theta angle = 0](https://tex.z-dn.net/?f=%20%5Ctheta%20angle%20%3D%200)
and radial component of given velocity is zero
we have![h = r_o v_r_o = 6378+600 =6.97*10^6 m](https://tex.z-dn.net/?f=%20h%20%3D%20r_o%20v_r_o%20%3D%206378%2B600%20%3D6.97%2A10%5E6%20m)
h = 6.97*10^6 *8333.3 = 58.08*10^9 m^2/s
we know that
![\frac{1}{r} =\frac{GM}{h^2} \times ( i + \epsilon cos\theta)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Br%7D%20%3D%5Cfrac%7BGM%7D%7Bh%5E2%7D%20%5Ctimes%20%28%20i%20%2B%20%5Cepsilon%20cos%5Ctheta%29)
![GM = gr^2 = 9.81*(6.37*10^6)^2 = 398*10^{12} m^3/s](https://tex.z-dn.net/?f=GM%20%3D%20gr%5E2%20%3D%209.81%2A%286.37%2A10%5E6%29%5E2%20%3D%20398%2A10%5E%7B12%7D%20m%5E3%2Fs)
so
![\frac{1}{6.97*10^6} =\frac{398*10^{12}}{(58.08*10^9)^2} \times ( i + \epsilon cos0)](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6.97%2A10%5E6%7D%20%3D%5Cfrac%7B398%2A10%5E%7B12%7D%7D%7B%2858.08%2A10%5E9%29%5E2%7D%20%5Ctimes%20%28%20i%20%2B%20%5Cepsilon%20cos0%29)
solvingt for ![\epsilon)](https://tex.z-dn.net/?f=%20%5Cepsilon%29)
![\epsilon = 0.22)](https://tex.z-dn.net/?f=%5Cepsilon%20%3D%200.22%29)
therefore eccentrcity of orbit is 0.22
Answer:
Context
Explanation:
It is of great value for an engineer to keep the context of his/her experiment in mind.
