Question : Which of the following is not a vector quantity?
Option 1: Speed
Option 2: Velocity
Option 3: Torque
Option 4: Displacement
Correct Answer: Speed
Solution : The correct answer is Speed.
While speed and velocity are measures of how fast an object is moving, they differ in that velocity is a vector quantity as it includes information about the object's direction and speed. Speed is a scalar quantity as it only

Question : If $2(\cos^{2}\theta-\sin^{2}\theta)=1$; ($\theta$ is a positive acute angle), then $\cot\theta$ is equal to:
Option 1: $–\sqrt{3}$
Option 2: $\frac{1}{\sqrt{3}}$
Option 3: $1$
Option 4: $\sqrt{3}$
Correct Answer: $\sqrt{3}$
Solution : Given: $2(\cos^{2}\theta-\sin^{2}\theta)=1$ ⇒ $\cos^{2}\theta-(1-\cos^{2}\theta)=\frac{1}{2}$ ⇒ $2\cos^{2}\theta=1+\frac{1}{2}$ ⇒ $\cos^{2}\theta=\frac{3}{2×2}$ ⇒ $\cos\theta=\frac{\sqrt{3}}{2}$ We know that [$\cos30°=\frac{\sqrt{3}}{2}$] ⇒ $\cos\theta=\cos30°$ $\therefore\theta=30°$ Then, $\cot30°=\sqrt{3}$ Hence, the correct answer is $\sqrt{3}$.
Question : In triangle RST, M and N are two points on RS and RT such that MN is parallel to the base ST of the triangle RST. If $\text{RM}=\frac{1}{3} \text{MS}$ and $\text{ST}=5.6 \text{ cm}$, what is the ratio of $\frac{\text { Area of triangle RMN}}{\text {Area of trapezium MNST}}$?
Option 1: $\frac{14}{15}$
Option 2: $\frac{15}{16}$
Option 3: $\frac{1}{15}$
Option 4: $\frac{1}{16}$
Correct Answer: $\frac{1}{15}$
Solution : Given: $RM=\frac{1}{3}MS$ ⇒ $\frac{RM}{MS}=\frac{1}{3}$ $ST=5.6$ cm Since $\triangle RMN$ and $\triangle RST$ are similar triangles. Then, $\frac{RM}{RS}=\frac{MN}{ST}$ ⇒ $\frac{1}{1+3}=\frac{MN}{5.6}$ ⇒ $MN=\frac{5.6}{4}$ ⇒ $MN=1.4$ cm So, $\frac{\text { Area of triangle RMN }}{\text {Area of trapezium MNST}}=\frac{\text{Area of triangle RMN}}{\text{Area of RST–Area of RMN}}$ Putting the
Question : Directions: Arrange the following in ascending order. 1. Centimetre 2. Kilometre 3. Decimetre 4. Metre
Option 1: 1, 3, 4, 2
Option 2: 2, 4, 3, 1
Option 3: 3, 1, 2, 4
Option 4: 4, 2, 1, 3
Correct Answer: 1, 3, 4, 2
Solution : Given: 1. Centimetre 2. Kilometre 3. Decimetre 4. Metre
The ascending order of units of measurement of length – Centimetre (1 cm)→Decimetre (10 cm)→Metre (100 cm)→Kilometre (1000 cm)
Therefore, the correct sequence is 1, 3, 4, 2. Hence, the first option is

Option 1: Rivers
Option 2: Earthquakes
Option 3: Volcanoes
Option 4: Mountains
Correct Answer: Earthquakes
Solution : The correct option is Earthquakes.
