AS Physics P1 MCQs Preparation Thread.

[Daniyal23]

you should do at least 5 so only 1 more paper

Thanx looks like i have to do all-nighter studying session.Since this is my last exam i wont mind

please help ....View attachment 12936View attachment 12934

for question 5
find the percentage error of each one and you will find that D has the greatest percentage error becasue it is multiplied by 2

Q4
you have to make sure both sides of the equation have the same units and the only answer which allows this is B

don't do that it would be better if you did a few and slept early and wake up early and did the rest papers tommorrow as it is proven that people who do all night studyers perfrom less

pls help me wid dis Q...

Is it A?

 

[raamish]

are the 3 formulas only applied when the acc. is constant. formula are v=u+at and v2=u2+2as and s=ut+ 0.5at2?

 

[bloody_mary]

how do v calculate the reading on a micrometer screw gauge in general? n also solve dis Questn pls....

and s= vt - at^2/2

 

[Peter Check]

Why did you do 2-4/3 ?

do you know why you did it??

 

[Peter Check]

HELP!!!! PLEASE!!

someone help of how to do this??? the answer is B

he said that the voltmeter reads 7.5..this means that 1.5V out of the 9V is lostdue to the internal resistance of the battery..then V=IR so I= 7.5 / 15 = 0.5A...HOPE I HELPED
