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!

ans????can anyone please explain this?View attachment 62515
Bans????
we first need to find the voltage in the external resistance. so using v=ircan anyone please explain this?View attachment 62515
Thankswe first need to find the voltage in the external resistance. so using v=ir
hence v=5.5v. since the all of the components are parallel to each other they all have an terminal potential difference of 5.5v
current going into the junction= output of junction.
so the current going into the internal resistance is 0.25A. 0.5/2 as both components have the same p.d and internal resistance they both have the same current
simply then use the formual
terminal p.d=Emf-Ir
5.5=6-0.25r
hence r is 2 ohms
when two objects collide elastically then relatice speed of approach = relative speed of seperationAnd this one too..View attachment 62516
thankyouwhen two objects collide elastically then relatice speed of approach = relative speed of seperation
• Same direction = subtract speed
•Opposite direction= add speed
answer=A
And this one too..View attachment 62516
lol beat me to itwhen two objects collide elastically then relatice speed of approach = relative speed of seperation
• Same direction = subtract speed
•Opposite direction= add speed
answer=A
15. mass=weight/gravityHelp with questions 15 and 29 please <3

is B the answer?
Its Cis B the answer?
lol CIE really tries to throw us under the bus.
Energy dissipatedis due to work done against motion f*v...2100*25= ans cIts C
wow ur fast. Can u solve my Q? ^lol CIE really tries to throw us under the bus.
2100*25=5.3kw
cause its asking about thermal energy so i guess you get that from the drag and friction
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.
