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...
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...
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.
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?
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...
