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:

Class : Class 7
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 2:

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..
