@mjc123 Yeah probably. Can you tell me what units should I use?

@HallsofIvy Actually I am pretty sure that I plugged in values having wrong units, that's why I just showed the values and what formula I am using. I just wanted to know what units are to be used in the formula.

We can calculate the average speed using this formula: uavg=root(8PV/ΠnM) I plugged in the following values: P= pi*10 atm (bar is approximately equal to atm) V=8lts n=2mol M=32*10^-3kg/mol But it is giving wrong answer. Can you tell me what went wrong?

So, I should apply pseudo force and follow the two steps, isn't it?

I can do the problem if the centre is fixed. The steps are: 1) Assuming tension in the string is zero at the top most position, we calculate the velocity at top most position by mv2/R = mg 2)Now, we simply apply mechanical energy conservation when the ball is at the top and bottom positions...

I am not sure, but I think the ground now should move downwards with 5 m/s relative to balloon.

I think that the stone should travel the entire 30 m distance that the balloon has ascended.

I solved it in ground frame like this: -30=5t-5t2, and then solving for t which comes out to be 3 sec.(displacement is 30 m downwards) Now, I am not getting the same answer when i am trying to solve it in the frame of the balloon. W.r.t. balloon, the initial velocity is zero, displacement is...

Using the given formula, meq of H2SO4 reacted= meq of salt = 5.205 The math is correct and I have verified it. Now, I am pretty sure that I am making a mistake in calculating the n- factor of the salt. According to the question, C4+6=4C+4 The n- factor is coming out to be 10, which is pretty...

Oh, so that's it. I guess I have to double check every answer key now. Thanks.

Oh, I see. So what's it going to be? I am still on (b).

I still see it as the minor diagonal of ABEF. Please help me.

It should look something like this. How should I proceed now?

We know that the sum of the two vectors is represented by the major diagonal. Now, if I draw the vector diagram, it turns out to be a diagonal of an entirely different parallelogram. So, my first answer was (c) none. But, I noticed that when parallelly shifted, it turns out to be the minor...
