Question : Which of the following is a characteristic of sedimentary rocks?
Option 1: Lineation
Option 2: Bands
Option 3: Foliation
Option 4: Lithification

Question : A student has to score 40% to pass. He gets 67 and fails by 13 marks. What are the maximum marks?
Option 1: 300
Option 2: 200
Option 3: 150
Option 4: 240
Correct Answer: 200
Solution : Let the maximum marks be 100%. According to the question, 40% marks are equivalent to (67 + 13) = 80 marks Now, 100% marks are equivalent to $\frac{80×100}{40}$ = 200 marks So, the maximum marks = 200 Hence, the correct answer is 200.

Option 3: Only conclusion II follows
Option 4: Both conclusions I and II follow
Correct Answer: Only conclusion I follows
Solution : The possible Venn diagram according to the given statements is as follows –
Let's analyse the conclusions – Conclusion (I): Some O are not P – It is clear from the Venn diagram that all P is W and no W is
Question : If $\cos \theta+\cos ^2 \theta=1$, find the value of $\sqrt{\sin ^4 \theta+\cos ^2 \theta}$.
Option 1: $\sqrt{2} \cos \theta$
Option 2: $2 \operatorname{cos} \theta$
Option 3: $\sqrt{2} \operatorname{sin} \theta$
Option 4: $2 \operatorname{sin} \theta$
Correct Answer: $\sqrt{2} \cos \theta$
Solution : Given: $\cos \theta+\cos ^2 \theta=1$ ⇒ $\cos\theta + \cos^2\theta = \sin^2\theta + \cos^2\theta$ ⇒ $\cos\theta = \sin^2\theta$ Putting the value in the given equation, $\sqrt{\sin ^4 \theta+\cos ^2 \theta}$ $=\sqrt{\cos^2\theta + \cos^2\theta}$ $=\sqrt{2} \cos\theta$ Hence, the correct answer is $\sqrt{2} \cos\theta.$

Question : Comprehension:
Read the following passage and answer the questions given after it.
The Indian Space Research Organisation (ISRO) announced another successful mission. ISRO chairman S. Somanath said that three small satellites successfully separated and were injected into orbit. ISRO launched three small satellites powered by its SSLV-D2 launch vehicle from Satish Dhawan Space Centre at Sriharikota on February 10, 2023, at 09:18 AM IST. The launch vehicle was carrying EOS-07, Janus-1 & AzaadiSAT-2 satellites and aimed to inject them into a 450 km circular orbit. The launch took place at the first launch pad at SDSC SHAR, Sriharikota. The SSLV-D2 had to take a 15-minute flight to inject EOS-07, Janus-1, and AzaadiSAT-2 satellites into a 450 km circular lower orbit. “It is configured with three solid propulsion stages and a velocity terminal module. It is a 34 m tall, 2 m diameter vehicle having a lift-off mass of 120 t,” said ISRO. The EOS-07 satellite weighs 156.3 kg and is made by ISRO.
About 13 minutes into its flight, the SSLV rocket ejected EOS-07 and soon after that the other two satellites Janus-1 and AzaadiSAT-2 were ejected — all at an altitude of 450 km, said ISRO.
With the new rocket in its portfolio, ISRO will have three rockets — Polar Satellite Launch Vehicle (PSLV) and its variants (cost about Rs 200 crore), Geosynchronous Satellite Launch Vehicle (GSLV-MkII cost about Rs 272 crore and LVM3 Rs 434 crore) and SSLV (Development cost of three rockets about Rs 56 crore each) and production cost may go down later.
“New experiments include mm-Wave Humidity Sounder and Spectrum Monitoring Payload. Janus-1, a 10.2 kg satellite belongs to ANTARIS, USA. An 8.7 kg satellite AzaadiSAT-2 is a combined effort of about 750 girl students across India guided by Space Kidz India, Chennai,” it added.
SSLV caters to the launch of up to 500 kg satellites to Low Earth Orbits on a ‘launch-on-demand’ basis. “It provides low-cost access to Space, offers low turn-around time and flexibility in accommodating multiple satellites, and demands minimal launch infrastructure,” as per a statement by ISRO.
