Real questions that test this

जीसॅट-7 (GSAT-7) हा पहिले नौदल उपयुक्त, उपग्रह केव्हा प्रक्षेपित करण्यात आला ? / GSAT-7, the first Navy user satellite was launched on

a)(1) ऑगस्ट 2013 / August 2013✓ Correct
b)(2) फेब्रुवारी 2011 / February 2011
c)(3) ऑगस्ट 2014 / August 2014
d)(4) वरीलपैकी एकही नाही / None of the above

GSAT-7, also known as Rukmini, is India's first dedicated military communications satellite for the Indian Navy, launched in August 2013 from Kourou, French Guiana.

पुढील विधानांचा विचार करा : / Consider the following statements :

(a)दूरसंचार उपग्रहाची गती पृथ्वीच्या गतीशी सापेक्षकपणे शून्य असते. / The speed of telecommunication satellite relative to earth is zero.

(b)म्हणून तो उपग्रह पृथ्वीवरील माणसांस स्थिर आहे असे वाटते. / Hence it appears to be stationary to a person on the earth.

1)दोनों विधाने चूक आहेत. / Both statements are false
2)(a) विधान बरोबर आणि ते (b) ची कारणमीमांसा आहे. / (a) is true and is a reason of (b)✓ Correct
3)(a) विधान बरोबर आणि ते (b) ची कारणमीमांसा नाही. / (a) is true and is not a reason of (b)
4)(a) बरोबर परंतु (b) चूक आहे. / (a) is correct, (b) is not

A geostationary telecommunication satellite has an angular speed equal to Earth's rotational speed, so its relative speed with respect to Earth is zero (statement a). Because its relative speed is zero, it appears stationary to an observer on Earth (statement b). Thus, (a) is true and correctly explains (b).

भारताच्या गगनयान मोहिमे विषयी अयोग्य विधाने शोधा : Find the incorrect statements about Gaganyaan Mission of India.

(a)गगनयान साठी भारतीय हवाई सेनेच्या चार वैमानिकांची निवड अंतराळवीर प्रशिक्षणासाठी करण्यात आली आहे. / Four pilots from Indian Air Force were short listed to be astronauts of Gaganyaan.

(b)त्यांचे प्रशिक्षण रशिया येथे युरी गागरीन कॉर्सोमेट सेंटर येथे होणार आहे. / They will be trained at Yuri Gagarin Cosmonaut Centre in Russia.

(c)या मोहिमेची घोषणा पंतप्रधानांनी 2014 मध्ये केली होती. / This mission was announced by Prime Minister in 2014.

(d)याचे नियोजन 2022 साठी पाच सदस्यांचे चमू एक महिन्याचे अंतराळातील वास्तव्य यासाठी करण्यात आले आहे. / It is scheduled for 2022 with team of 5 crew members and a month long stay in space.

1)(a), (b), (c), (d)
2)(b), (c), (d)
3)(c), (d)✓ Correct
4)(b), (c)

Gaganyaan was announced by the Prime Minister in 2018 (not 2014), and it is planned for a 3-member crew (not 5) for a duration of 3-7 days (not a month). Thus statements (c) and (d) are incorrect.
