souvik is saying 'avoid giving water to the person in case of poisoning so the poison does not spread in the body. and tying torniquet just above the wound will spread the poison more. so, the answer should be C

ADRIJA SAHA from DPS RANIPUR, Haridwar

Read the given statements and select the correct answer.
Statement 1 : The distance x at which a car can be stopped by applying brakes depends on the initial velocity.
Statement 2 : Mass of the car has no role to play.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.
D Both statements 1 and 2 are false.


mass of the car has role to play due to momentum.

Ans 1:

Amishee Surya from bgsnps, Bengaluru
Class : Class 8
C is the correct answer. Force is applied to stop the vehicle. The formulae of force is mass * acceleration. Acceleration is final velocity - initial velocity by time. F= M*{(v-u)/t} and its kinetically equation is F=M *[v square - u square/ 2 * distance]. Which ever formula for force has been taken MASS is important. So clearly MASS HAS A ROLE TO PLAY. hence the answer must be C

Ans 2:

Raavi from DPS, Ranchi
Class : Class 8
c is the correct answer and solution is also given in favour of option c. but answer is b

Ans 3:

Pranav Prakash from SSSVV GAIL Vijaipur, Guna
Class : Class 9
Apropos to the question the mass of the car has a role in the momentum of the car, as Momentum=mv ,therefore option 'C' should be the correct answer.

Ans 4:

TRIYA SOUMIK NATH from SYMBIOSIS PRIMARY SCHOOL, PUNE
Class : Class 6
Though it looks like mass has no role to play in braking distance, actually coeff of friction (COF) between tyre and road surface has inverse relationship with braking distance. COF depends on normal force due to weight of vehicle and therefore indirectly mass plays a role on braking distance. The correct answer should be C

Besides the arrangement as shown in the given set-up, what other arrangements must be made to test for the presence of starch in the leaves X and Y ?


A The plant should be destarched first and then used for the experiment.
B The plant should be placed in continuous light for 2-3 days prior to experiment.
C On leaf Y, iodine solution should be put on while leaf X should be used as control without iodine application.
D None of these


I suppose it should be placed in dark for destarching and then in sunlight for testing whether the plant can perform photosynthesis in absence of CO2..
