oh okay but can you please explain why it will be a different system? i mean i am taking the mass of gas from the same system, just keeping the volume same. i am just not able to visualise it i think, can you give a basic definition of what system is and what it constitutes?

hello everyone, recently i was studying thermodynamics and i think i got a basic doubt on what my book has to say and although i feel this is a small thing to ask but since i have no teacher with me, this is the best place i can think of. so my book was saying about intensive and extensive...

duh! lol that was really a simple one xD but thanks everyone for giving a good explanation :)

hi all so this is a very basic question i think and i feel very bad for tumbling here but still i need to clear this, so from childhood i was taught that the negative numbers are less than positive but now when i am studying limits and functions i came across absolute function and it said |-x| =...

I learned that differential of e^x is same but what's so special about it? What makes is so special as it seems like a normal function to me other than the fact that e= sum of series of reciprocal of factorial numbers. What i want to ask is if e^x differential is e^x then do this rule apply to...

thx for verification, i was thinking i can't use equations of motion here as they are for 1-d motion but here we are working in 2-d plane. Also can u please tell me why do tan theta = coefficient of friction was not working here? what was i doing wrong there? thanks

Hi, sorry for late reply. Was busy with my assignments. I did the solution this way in the pic below pls tell if its correct. I feel I can't use equation of motion here which I did.

yea, i read the forum rules, sorry fr my ignorance. but the problem is i am not able to arrive at final solution. i tries to create 2 equations by taking the slope of inclined plane as x-axis and normal as y-axis but still i wasn't getting adequate data to solve 2 variables. it still requires...

how can i do that? the body is not at rest and i can't balance any equilibrium forces. can you please provide me with a full solution. that would be really helpful. :)

then please help me how to solve this question? i am really stuck at it.

its valid here by geometry. i can't show u by drawing a diagram here but if we draw a fbd of mass on inclined plane and forces acting on it then by equation ##\mu= frictional force / normal force. we can have tan theta = cofficient of friction.

Homework Statement A particle of mass M is released from rest on a rough inclined plane, which makes an angle of 30° with the horizontal. It is observed that the particle moves a distance of 3 m in 3 s. What is the particle’s acceleration? Draw a properly labelled free body diagram. Calculate...
