Homework Statement : [/B]Write a C program to print hello world 2. The attempt at a solution: I am completely new to programming. I am learning C at present. In my college, we use linux. Since my pc has windows installed so I am using cygwin terminal to use linux commands from windows. I am...

apparently 10how is that possibleit can hold at max 8 if I'm not wrong

I have uploaded the picture of the structures because I couldn't figure out how to type. Its vinyl chloride. According to me the order should be I>III>II because I has no charge so it must be most stable in II we have Cl an electronegative element bearing positive charge which makes it...

They have equal component of acceleration in that direction? Equal in magnitude. not sure of the sign. should have same sign as well. if they stay at constant distance apart, then relative acceleration should be zero in the direction tangential to the string ? But which of the three equations I...

[emoji28]

By “string has constant length” do you mean the string remains taut and does not get slack at any point of time or do you mean it is unstretchable? Can you give a little more hint?

i am so sorry, it will be 80 and I have written 60. I am so sorry...I have got the answer now...I have this exam in a week and i don't know what will happen if i do mistakes like this. Thank you sir for your patience and helping me out. And also for reminding me of this concept. Thank you so much.

i guess mc=mg-TCosθ mb=Tsinθ since centre of mass should not accelerate, i guess a=b

But answer is not matching. They say its 380/13 for capacitor C3.[emoji27]

mgCosθSinθ/M=10/2=5m/s² but that is not the answer, the answer given is 10/3

mgCosθSinθ? Sorry for my poor handwriting. But I think according to the FBD i have sketched, Tcosθ=mg. and not T=mgCosθ

40, 30, 10 are the potential difference applied to charge the capacitros, not the charge itself. Initially total charge is 60+90+40 = 190 ? so charge on capacitor 2 is 190-(20+x +x-40)? = 190-( 2x-20) =210-2x Am I correct now?

By “it” i meant the cart, not the centre of mass. Can you please rephrase your question a bit?[emoji28]

That is the reason I’m confused. Vertical acceleration of block B is g? or is there some centripetal force acting whose vertical component gets added up?

Homework Statement : A block B of mass m is suspended from a cord of length l attached to cart A of mass M as shown in the figure. The horizontal surface on which the cart moves is smooth. Initially the cart and the block are at rest in the position shown. Now the block is released. Take M=2kg...
