Q2. Esterification is the reaction of one of the below compounds with alcohol
Answer : Option A
Explaination / Solution:
Carboxylic acid and alcohol reacts to form an ester.
Q3. A parallel combination of 0.1 MΩ resistor and a 10 μF capacitor is connected across a 1.5 V source of negligible resistance. The time (in seconds) required for the capacitor to get charged up to 0.75 V is approximately
Answer : Option A
Explaination / Solution:
A capacitor is charged when the resistance is connected in series with the capacitor. The time constant of the circuit . The capacitor will not be charged.
Q4. There are ____ L in 0.05 ml?
Answer : Option D
Explaination / Solution:
Since , 1L
= 1000mL
or , 1mL
=.
0.05mL
=
= 0.00005 L .
Q5. One factor that causes a movement along the demand curve of a commodity
Answer : Option C
Explaination / Solution:
No Explaination.
Q6. A particle is orbiting in a vertical plane. Its linear momentum will be directed
Answer : Option D
Explaination / Solution:
As the direction of velocity at any point moving in circular orbit is tangent at that point, thus momentum would be tangential to the orbit.
Q7. Two match sticks are laid side by side on the surface of water. When a drop of light oil on the end of a third match stick is touched to the surface film between the two floating sticks, the two match sticks
Answer : Option D
Explaination / Solution:
No Explaination.
Q8. In frog, during aestivation and hibernation gaseous exchange takes place through
Answer : Option C
Explaination / Solution:
As the frog becomes inactive during aestivation and hibernation, gaseous exchange does not take place through lungs. It takes place through skin.
Q9. The name virus was given by
Answer : Option B
Explaination / Solution:
The name virus that means venom or poisonous fluid was given by Pasteur. They are inert outside specific host and living inside the host cell. Viruses are obligate parasites.
Q10. for motion under an external conservative force
Answer : Option D
Explaination / Solution:
Mechanical energy is the sum of the potential and kinetic energies in a system. The principle of the conservation of mechanical energy states that the total mechanical energy in a system (i.e., the sum of the potential and kinetic energies) remains constant as long as the only forces acting are conservative forces.
