We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Delta L is amount of compression. If amount of compression is high then length of object drcreases.and vice versa.Could you elaborate?
View my previous posts by the upward arrow.Could you elaborate?
More current = More brightness
It has traveled 100 miles in the y direction till 12:30.Fom 12:00 to 12:30 distance coveref is 100 miles
From 12:30 to 1:30 distance covered is 200 miles.
Total distance covered = 300 mile so outside of range of cambridge
Remaining distance to covere = 80 mile but we only have fuel for another 50 miles since fuel for 300 miles is used up so emergency langding.
and 31?More current = More brightness
Since if you open switch then current will no longer be divided so the current flowing in the main branch will increase. Main branch is branch containing b1 and b2
What is the answer? A or B?and 31?
but the ans is CInitial KE: 0.5*m*v^2 = 0.5mv^2
Initial momentum = final momentum
mv = 2m(final velocity)
final velocity = v/2
Final KE: 0.5 * 2m * (v/2)* = 0.25mv^2
AWhat is the answer? A or B?
bcx it takes more time to return to XY less tim isnt possible possible as it rolls upwardsWHy is option B wrong??View attachment 54934
As the ball moves from X-Y, the speed is increasing uniformly. From Y-Z, it has a constant speed. They say that the collision with the wall is inelastic. So, the rebound speed is lesser than the impact speed. v=s/t When v decreases, that means that t increases. Longer timeWHy is option B wrong??View attachment 54934
Distance YZ is constant.WHy is option B wrong??View attachment 54934
Yes, its the net work doneThe shaded area is the total work done right?
I don't know how to differentiate between A /B. Anyway Volt is defines as Joule per Coulomb. 9 V = 9 Joule per coulomb.
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.
