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

Ans 2:

Class : Class 6
I think answer is wrong , use of tourniquet was preferred method until few years ago , it has been found it can damage blood flow and nerves

Ans 3:

Class : Class 6
answer is wrong because if we apply tourniquet it may damage the nerves. the poison will remain its place but it may kill all the cells there

OPTION OF ANSWERS ARE WRONG. SIMMI AND SAMRAT HAVE MADE WRONG STATEMENT

Answer is wrong

Ans 7:

Class : Class 5
the options are wrong...... even the explaination is wrong

Ans 8:

Class : Class 4
Answer is wrong, Souvik is saying 'avoid' while the answer is giving a different explanation .All Samrak, Souvik and Shivani are wrong.

Ans 9:

Class : Class 5
answer is ok.

Ans 10:

Class : Class 6
I think answer is wrong. Shivani is also right. Using a tourniquet prevents the poisoned blood from reaching the heart.

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 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:

Class : Class 8
c is the correct answer and solution is also given in favour of option c. but answer is b

Ans 3:

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 4:

Ans 5:

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
