Plz explain why here positive sign with work done * in 50 cycles? x1o 5 f a : lw a =afav w w-(xo)o d6 s. w +36o00t o.0im

for clockwise work is positive and anticlockwise work is negative

sir plz check my answr

yes it's correct

👍👍

please accept the answer if you got it 🙏🙏

check this mam

ok mam

m sending u again

this

plz che k mam

?

but mam

here answr is positive

?

yes

physics hai

thanku

yes this I know but sign

yes it is positive here...clockwise it is here in cyclic process

simply you can also do here from B to C work done and from D to A work done...and subtract it as direction of rotation changes here..you will get same work as you get by multiplying length and width

plz check this

negative aayega

no shweta here direction of rotation matters as it is cyclic process

got it shweta...see here you are going from B to C change in volume is what the upper minus lower but from D to A the change of value is lower minus upper

see direction of rotation

yes sir but b to c us expansion and expansion work is negative

and d to a is compression it's work is positive

here we are considering cyclic process so take whole process shweta...A to B to C to D..clockwise manner

here they are not considering expanation ,compression only they are using direction of rotation

right

as it is cyclic process, so here direction of rotation matters

ok

please mark the answer too shweta if it helps 😊🙏

see this

yes shweta here area under the curve gives works...you know that much

ok

shweta these images are able to clear your understanding in confusion about sign convention...read this

thanku

couter clockwise means

anti clockwise

ok

got it shweta??
