Yeah I was a bit skeptical about that. I think I only got one question wrong. I calculated the resistance correctly then thought it wrong and changed it.yes, it can.

i wrote fr fiction force opposing body in motion and what u wrote why acceleration decreases as he moves along level road
air resistance increases , is greater than forward force.i wrote fr fiction force opposing body in motion and what u wrote why acceleration decreases as he moves along level road
There was no need to write the poles, they just said to draw mg fields .round the iron core.
just didn't write the poles.
i wrote friction increases between tyres and roadair resistance increases , is greater than forward force.
unbalanced forces , so , acceleration decreases
is it righti wrote friction increases between tyres and road
i dont know mate. Just hope for the bestis it right
I think that air resistance did not get greater than the forward force, it just increased to near the forward force decreasing the resultant force, hence the acceleration too.air resistance increases , is greater than forward force.

lolI think that air resistance did not get greater than the forward force, it just increased to near the forward force decreasing the resultant force, hence the acceleration too.
It did not said deceleratelol
even if it nears the forward norce , it will not decelerate since it has not overcome the force.
it has to be greater then the driving force to make it decelerate.
say * D:It did not said decelerate
It said acceleration decreased, which was obviously going to be that the air resistance force increased to the magnitude of driving force, decreasing the resultant force.

Pray to ALLAH for a good grade.
now if you'll excuse me, i've got to prepare for chemistry
well why would it btw ?? it should return to its original position at 0Q 9 part d you did it wrong, when switch will be opened, the deflection would be on the left ! (momentarily)
first of all keep in mind that the graph was a speed time graph and it wasn't the height of the hill as it looked confusing bcuz of its hilly shape and people naturally felt the answe rwill be A or C or D as it said bottom of the hill.Why was the answer to the hill one B ?
Thnxfirst of all keep in mind that the graph was a speed time graph and it wasn't the height of the hill as it looked confusing bcuz of its hilly shape and people naturally felt the answe rwill be A or C or D as it said bottom of the hill.
then keep following that he is at the bottom of the first hill.... all the gravitaional potential energy is converted to kinetic energy. speed is directly propotional to kinetic energy so here it has the highest speed and the highest speed was B. hope it explained
No they only check first two !i attempted three questions in sec. B ... do they check all three.?
Wht was the answer to the centre of mass one ?first of all keep in mind that the graph was a speed time graph and it wasn't the height of the hill as it looked confusing bcuz of its hilly shape and people naturally felt the answe rwill be A or C or D as it said bottom of the hill.

For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
