Question : A person can jump higher on the moon's surface than on the earth because :
Option 1: The moon's surface is rough
Option 2: the acceleration due to gravity is smaller than that on the earth
Option 3: the moon is cooler than earth
Option 4: the moon has no atmosphere
Correct Answer: the acceleration due to gravity is smaller than that on the earth
Solution : The correct option is - the acceleration due to gravity is smaller than that on the earth
The gravity of the Earth is six times stronger than that of the moon. This shows that
Question : Directions: In the following question, select the related number from the given alternatives. 21 : 3 :: 574 : ?
Option 1: 23
Option 2: 82
Option 3: 97
Option 4: 113
Correct Answer: 82
Solution : Given: 21 : 3 :: 574 : ?
Divide the first number by 7 to obtain the second number in each pair. Like, 21 : 3→21 ÷ 7 = 3 Similarly, follow the same pattern for 574 : ?→574 ÷ 7 = 82
So, 574
Question : The 'Choke' used with a tube light is basically
Option 1: an inductor
Option 2: a capacitor
Option 3: a transformer
Option 4: a resistor
Correct Answer: an inductor
Solution : The correct option is an inductor.
A choke is an inductor used in electronics to transmit lower-frequency or direct current (DC) while blocking higher-frequency alternating current (AC) in an electrical circuit. When the current in a choke, which is linked in series with
Question : The chemical formula of propene is:
Option 1: C2H4
Option 2: C3H4
Option 3: C2H2
Option 4: C3H6
Correct Answer: C3H6
Solution : The correct option is C3H6.
Three carbon atoms and six hydrogen atoms make up propene. Propene has a single bond from the centre carbon to the free carbon, followed by a double bond from the middle carbon
Question : $\frac{1+\cos \theta-\sin ^2 \theta}{\sin \theta(1+\cos \theta)} \times \frac{\sqrt{\sec ^2 \theta+\operatorname{cosec}^2 \theta}}{\tan \theta+\cot \theta}, 0^{\circ}<\theta<90^{\circ}$, is equal to:
Option 1: $\sin \theta$
Option 2: $\cos \theta$
Option 3: $\operatorname{cosec} \theta$
Option 4: $\cot \theta$
Correct Answer: $\cot \theta$
Solution : $\frac{1+\cos \theta-\sin ^2 \theta}{\sin \theta(1+\cos \theta)} \times \frac{\sqrt{\sec ^2 \theta+\operatorname{cosec}^2 \theta}}{\tan \theta+\cot \theta}$ $=\frac{1+\cos \theta-(1-\cos ^2 \theta)}{\sin \theta(1+\cos \theta)} \times \frac{\sqrt{1+\tan ^2 \theta+1+\operatorname{cot}^2 \theta}}{ \tan \theta+\cot \theta}$ $=\frac{\cos \theta+\cos ^2 \theta}{\sin \theta(1+\cos \theta)} \times \frac{\sqrt{(\tan \theta+\operatorname{cot} \theta)^2}}{\tan \theta+\cot \theta}$ $=\frac{\cos \theta(1+\cos \theta)}{\sin \theta(1+\cos \theta)}
Question : If cells are kept in a solution and the net result is that the cells swell up, then the solution is_____.
Option 1: Hypertonic solution
Option 2: Isotonic solution
Option 3: Hypotonic solution
Option 4: Acidic solution
Correct Answer: Hypotonic solution
Solution : The correct option is the hypotonic solution
A hypotonic solution has less solute than the solution on the other side of a membrane. Water from the surrounding solution enters the cells, causing them to expand and potentially explode.
Question : For which year was Manna Dey honoured with the Dadasaheb Phalke Award?
Option 1: 2015
Option 2: 2019
Option 3: 2007
Option 4: 2001

Question : Recharging of water table depends on
Option 1: amount of rainfall
Option 2: relief of the area
Option 3: vegetation of the area
Option 4: amount of percolation
Correct Answer: relief of the area
Solution : The correct option is relief of the area.
The recharging of a water table is closely linked to a region's relief or terrain. The topography of a region influences how water interacts with the terrain and, as a result, replenishes underground aquifers.
