use p=nRT/V the intPdV will be nRT(ln(V2/V1))

friction on on circular objects while rolling?? i had a doubt about circular rolling objects.. it is true that friction opposes relative motion..but while doing so in a rolling wheel rolling forward,the friction also works in forward direction.so then my question is why does the wheel stops...

ah,dave can you please explain elaborately,in which part I'm wrong.this will also help me!

if moon suddenly disappears ,then as we know weak and slower tides will be there,we will have faster rotation due to absence of gravitational force on earth, which consecuently increase and resizes Earth's radius resulting in slower angular velocities.also the trajectory of Earth might change if...

this is what i acctually wanted to say as the main reason why both don't collide.this is the wobbling effect i was talkin' abt..

before answering your question,there are some essential things that you should know. 1)than due to rotation,our Earth becomes an accelerated frame,so as long as we are on it we experience a pseudo force that has a value of mv2/r.here r depends on our coordinates as at defferent places on Earth...

actually the COM of the earth-moon system lies inside the Earth's mass.as both of the Earth and moon pull each other with equal forces,the both wobble around itself.now this wobbling is the main reason why they both don't collide.they wobble in a way in which when the moon approches Earth by the...
